Just in case you haven’t heard about it, today is the day of the 2024 Total Solar Eclipse. We would like to think that our newsletter is so good that you feel it’s the only source of information you need, but that would mean you are just now finding out it is going to get dark this afternoon! Our main customer base is not in the arc of totality. I believe we are only going to hit 97%. So, for us, it’s mostly been business as usual. A couple of weeks ago, I heard that some of our customers are expecting an influx of people into their area of up to 2 million! There have been a lot of recommendations in the news on how to best enjoy this rare event in our area. I hope that you make the best of it. 

But since we’re in the business of plants, I’d like to ask you…
What would you consider a “Total Eclipse of a Plant?”

In the ever-changing annual market, they have bred for sun tolerance in Begonias. In recent years, Proven Winners has brought on the Double Delight and the Solenia Begonias. Both series are recommended for sun to part sun. They aren’t recommended for shade at all!

But my question is, “Why?”  So many plants are sun tolerant already.  Shade varieties are the minority and need to be sought out for troublesome spots in the landscaping.  Where are the shade-tolerant Coneflowers? How about a good tall shade-loving Ornamental Grass? Why are we breeding (in my opinion) in the wrong direction?

On the other side of the moon, are there sunny plants eclipsing themselves by taking some shade? Who is trying to bring the bright colors of roses into the dark corners of the garden? David Austin, that's who. His English rose collections have some full sun roses that will take shadier locations. Some of Dave’s roses only need 4-5 hours of sun. Ironically, one of them is called “Bring Me Sunshine”.  They are a step in the right direction of bringing more plants over to the shady side. 

Now, that’s what I call a total eclipse of a plant!

In late fall, besides the trees changing colors, you will also notice a change in your perennials. In this article, I would like to discuss fall perennial practices. Topics will include fall cleanup, which perennials should be cut back vs. which should not, perennial varieties that provide habitat for local wildlife, and how we close up the perennial greenhouses in the nursery. These tips should help with the overwintering process.

On the flip side, there are a few arguments for leaving some perennials in your garden alone. To protect the habitats of birds, and beneficial insects, you could consider not cutting Rudbeckia, Echinacea, Eupatorium or perennial sunflower. These seeds will provide food throughout the winter. If your home is close to wooded areas, meadows, or contains a brush pile, your garden may be even more habitat friendly. Some perennials that I would not cut back in the fall would be Asclepias, Ferns, Heuchera, and Dianthus. This is to protect the crowns during the harsh winter. Perennials are more cold-hardy when their stems are left intact. These stems can trap in snow, and work as an insulator for their crowns. A quick clean-up in the spring, and these will be just fine. The last reason why I would consider leaving some perennials be, would be their winter interest. Some stuff just looks awesome covered in snow! Species with stiff stems, or flat or cone-shaped dried flowers have a great winter look! Things like Sedum Autumn Joy, Ornamental grasses, or Echinacea Purpurea add to a garden’s winter beauty!

It is also not uncommon to line an entire house with some of those winter tolerant varieties to both save space, and act as a buffer for other material. We also have one heated structure that we use to protect our grasses (mainly Miscanthus, and Pennisetum varieties), from ever freezing. By keeping minimum heat on our grasses, we are ensuring a healthy, happy grass come spring.

Whether you are overwintering perennials in your landscape, or at your nursery there are many factors to consider. Moisture, temperature, snowfall, and sometimes just plain old luck are all factors that will determine how your perennials fare over a long winter. Keeping in mind potential winter damage, bird and insect benefits, and most importantly, what’s best for the plant, will ensure a seamless transition to the brisk winter days! Happy spring clean ups!

What is more beautiful than Michigan in the fall? The colors around this time are brilliant! What can you do to bring that fall color home? You can consider some stunning fall-blooming perennials. One often overlooked aspect of perennial gardening is planting varieties with different bloom seasons- including fall. This is important because perennial blooms often have a short life span. Sometimes as short as two weeks! By keeping the seasons in mind when planting, you can ensure a captivating landscape with showy perennials all season long. Let me highlight my favorite fall-blooming plants and why they should be added to your next project.

Let’s start with an obvious one. An oldy but goody- the fall mum. Mums are perfect for fall because they bloom later in the season-August-October. This is usually around the time other perennials just finish their bloom cycle. Although there is debate on whether mums are perennial (best luck when insulated in the ground), they are also used in pots, or on porches for those spooky fall months. If dead-headed, you could extend the life of your mums to last the whole fall season. Available in red, orange, yellow, purple, pink, and white, fall mums will be arriving here at Christensen’s at any moment.

Another fall favorite is Anemone. Most Anemone varieties take some time in the spring to show any growth, so if you have some in the ground, do not fret if you do not see growth right away. There is an exception for the Anemone Sylvestris which is a spring blooming variety. The late bloomers don’t show color until around August and last through the fall. Varieties like ‘September Charm’, ‘Elfin Swan’, or ‘Robustissima' are a great choice. Ranging in color from white, pink to red, with adorable Daisy-like flowers, these are a perfect choice to fall.

Asters are another perfect option if you are looking for fall color. There are two different types of Aster- New York, and New England varieties. In general, New York Aster are shorter with thin  

The last plant I would like to highlight is Perovskia (Russian Sage). Perovskia comes in all shapes and sizes. Over the years, we have trialed many varieties to determine which can withstand the heat. One of the best varieties out there is the Perovskia Blue Jean Baby. Growing to 3x3 ft tall and wide, this one is great because it maintains it shape, and doesn’t get too floppy. These lavender flowers and silver foliage last all the way through fall. They also have a pleasant sage-like smell. Find varieties like Blue Jean Baby any time at the plant center.

Welcome back – I hope that everyone had a great holiday. Whew! Spring is finally over! For me, summer is a time of slight relaxation. 2023 is humming along and I have a month until I must start 2024. (Let’s not think about that!).

I wanted to check with everyone and make sure you all saw some of the new plant varieties at the nursery – if not, come on in as there are more newbies here and incoming.

There are a couple of new plants that I am excited about. Of the hundreds of new cultivars every year it is hard to know what to choose. Sometimes, I throw dice, sometimes I look at the magic 8-ball, and sometimes it has to do with a catchy name (I am a sucker for a catchy name!). Then I do some research and decide if the name is catchy enough! Check some of these out:

I have a couple of newer grasses this year, as well. My favorite is the Andropogon gerardii cultivars. Check out ‘Holy Smoke’ (Cheech and Chong movie ??), ‘Blackhawks’ (again with the movie?), and Red October (another movie!). ‘Holy Smoke’ and ‘Blackhawks’ both are going to be 4-5’ tall and ‘Red October’ is a dwarf coming in at 2-4’. All 3 are native prairie grass and rock hardy. All 3 also have purple-green leaves and get varying shades of red from mid-late summer through fall.

I also have a couple of new Hydrangeas! Please don’t tell Chris!!! They are a secret. The one I am most excited about is Hydrangea paniculata ‘Puffer Fish’, “a Bobo on steroids”! It has white flowers that age lime and pink. They will typically send another flower at this same time and rebloom over top of older blooms. It gives the effect of double flowers – very showy. It seems everyone likes the compact habit of the ‘Tuff Stuff’ so take a look at this one ‘Pop Star’ . This one is from the Endless Summer people. This is a typical blue or pink lacecap (macrophylla). However, ‘Pop Star’ is far more compact (and looks far denser) than the traditional ‘Endless Summer’. Its biggest claim to fame is that it reblooms much faster than a traditional ’Endless Summer’.

Unfortunately, I haven’t been able to get my hands on Jeffery’s Weigela ‘Bubbly Wine’. If you were unaware, Jeff Good is now the patent holder of Proven Winners® Weigela ‘Bubbly Wine’. I will let him tell you all about it. I on the other hand will tell you about a relative of Weigela ‘Midnight Wine’ with darker, shinier burgundy leaves and a 12’ tall about 3’ wide habit. W. ‘Midnight Wine Shine’ is also much denser. Finally, W. ‘Very Fine Wine’ is a dwarf – 30x30” with better hardiness and heavier rebloom.

Before I let you go – let’s talk Ilex crenata ‘Sky Pencil’ I have not grown this personally and we have not had it at the nursery before. Everyone is yelling at me about this plant. Everyone wants it and I keep saying it is not hardy enough for us, you keep saying it is! I have special ordered this plant in the past and those that have put it in the landscape have told me they are hardy. So, this year I will stock a few. Ilex crenata ‘Sky Pencil’ is a female ilex and will need a pollinator to bloom (any ilex that blooms at this same time will work.) ‘Sky Pencils’ get to be about 6-8’ and 2’ wide – yes, with a very columnar habit. It is a very dense tightly branched shrub. Considered a solid zone 6 possibly a zone 5 – it may all depend on the winter. Berries or not, it is a good-looking plant!

Have you tried these new varieties? Let us know what you think of them! We welcome your feedback on the plants we stock.

I hope to see you around the plant center, checking out all the new stuff!

I am missing flowers (both literally and emotionally).

How can I work for a plant nursery and have zero blooms in my yard in the middle of summer? (Maybe because I work for a plant nursery?) I get so excited at the beginning of the season with all the pretty things coming in that I take them all home and plant them. Tulips and Daffodils, Hellebores, creeping phlox’s, Dicentra. Stunning. And then what happens? After the blooms fade and the ephemerals die back, I end up with a lot of green. And then… nursery life goes into full swing and by the time I get to slow down and catch my breath, it is mid-summer.

Where is my color? I need plants. Taking a walk through our perennial lot I notice all the plants that are in full sun with beautiful flowers. I want that! Easy choices are the Rudbeckias. Echinaceas, and Hemerocallis. But what are some less obvious selections? My flower beds have some time in the shade, so in order to get the best show of color, I need varieties that can handle both. So, on my walk, I took a few notes.

Geraniums are a good choice. Full sun or part shade, “Rozanne” can be a good rambler. I need to fill in some space and I know she’s about 20” tall by 28” spread. Very low maintenance and long-lasting blooms throughout the whole season can guarantee a nice show of color through these dog days of summer.

Astilbe’s have always been one of my favorites and we offer a wide array of sizes and color. I’m a big fan of their fluffy, showy flowers. Although we have them in full sun, Astilbe’s actually prefer a bit of shade to cool them down after a long hot day.

Our Chelone “Hot Lips” are just about to pop. 2’-3’ feet high and a 1’ spread, these are great to add a backdrop or color to a dull corner. These will be perfect for this time of year! They can grow in drought conditions until established or they can grow in bog or rain gardens. They are low maintenance and will handle the full sun or partial shade.

Heucheras, I think, are going to be a staple. With many varieties to choose from, they are a great, easy way to tie any color combination into the landscape. Different heights and sizes will be perfect to tuck in around the taller plants. And again, heucheras prefer part shade, can handle sun, like it a little dry. Perfect for my needs!

There is a theme here- low maintenance and lots of color!

And finally, ground cover! Of course, some of that “green” in my yard are weeds. Since I really don’t have a lot of time to throw down mulch every year in the spring I’m going to have to plant something. We have lots of choices here at Christensen’s, however, I have found that Lamium is a great choice for spreading. Vigorous but not invasive, the two-toned foliage is striking and can fill in quickly throughout the season. If I was just looking for a colorful addition, I'd go with 'Orchid Frost'. But, I’m thinking the 'White Nancy' may be a great addition to brighten up and throw some definition into the mix.

I now have a few choices. But there are so many more! Seriously, it’s like choosing a paint color. I know if I took another walk through the perennial lot or into the Hosta House I will have a whole new set of plant varieties, colors, and textures to take home and play with! The choices are plentiful!

Christensen’s Plant Center has a wide range of departments. One of them being the Perennial Department. Known to most as “The Perennial Girls”, we are the group that receives, grows, and maintains the stunning perennials you see around the nursery. This includes the beautiful material on the Perennial Lot, roses, grasses, and more! I'd like to introduce you to the Perennial production department, and all that goes into ensuring you have the best possible perennials to meet your landscape needs.

Some of you may not know, but as well as bringing in perennials fully grown plants off trucks, some of the perennials you find around the nursery are produced right here on our property. Our “west” location has greenhouses that switch over from winter storage to perennial production as the weather breaks. Spring is our busiest time. We spend our weeks potting up as much as possible, so that come summer, we have plenty of dazzling product. We grow a wide range of perennials, grasses, and even some shrubs. This spring, we even potted up some Boxwood varieties with big hope for success!

Soil mixes (which have been trialed over time), pot sizes and types, and water needs are all things taken into consideration in the production department. Hemerocallis Stella, Hosta Patriot, Heuchera Palace Purple, and Nepeta Walkers Low are all production favorites. These staples are always growing in production as a backstock to ensure that we always have some on hand. With the inventory shortages industry wide, this back stock can also come in handy when large quantities are unexpectedly needed.

Aside from the staples, we also grow some specialty items such as Peony, Dianthus, and other “funky” varieties. These diverse items are some that we have trialed over time and have proven to do well with. Being able to provide what is needed as availabilities change, is a huge benefit to the Production team!

Perennial production is a flexible department, that can adjust to both industry and customer needs. We work hard to grow and maintain our perennials to ensure that we have a fabulous product year-round! Head over to the “Perennial Girls” for all your perennial questions and needs. 

When I was growing up my father and I planted gladiolus corms in our flower garden next to the house. I remember their bold colors reliably displaying each summer. When I moved into my own home years later I found all sorts of new and exciting colors available. They were beautiful that first year, but the following year I noticed that most of my glads didn’t come back. After some internet-sleuthing I realized that they are supposed to be lifted and stored inside for the winter. So why did they always come back when I was a kid?

Microclimate perhaps? Our main flower garden was against a south-facing brick wall, with years of compost mixed into our sandy soil. Glads don’t like a wet bum, so our native, well-drained soil was a good match. The sun-exposed brick wall warmed up the soil, tempering the chilly winter ground.

Could it have been the heirloom varieties we grew? I’m generally a believer that local heritage varieties are hardier. This seems to be the case with gladiolus. In my experience the new fancy ones, though beautiful, are hit-or-miss with successfully overwintering in our area.

Here are some tips to help you on your way to beautiful spires of color each year:

Plant in pots

Be sure your pots are large and heavy enough so the flowers won’t blow over, also make sure they have drainage holes. Add rocks to the bottom of the pot, top with a sandy soil mix. For an extended blooming season plant pots a couple weeks apart, or mix varieties in the same pot. You can add supports to help the spires stand up as they grow tall. There are shorter, and even dwarf varieties available that may work well in pots without support or the fear of wind damage on balconies. After the flowers are spent it could be a good time to move the pots somewhere less conspicuous, as the plant does not rebloom. Sometime before the first frost, dump out the pots and collect the corms, set them somewhere where they can dry in the open air for a couple days, then lightly cover them up to dry further. For final long-term winter storage place them loosely in layers in a cardboard box, separating layers with newspaper. Keep them in a cool dark place where they may nap until spring, protected from animals and sub-40f temperatures.

Leave ‘em in the ground

With a little bit of luck and some forethought you can have success simply leaving your glads in the ground! Moisture and extreme cold temperatures are what you’re trying to manage. To this end, I have found that digging trenches in sunny areas that are not prone to spring puddling works out well. Planting next to a sun-exposed wall is even better! Dig the trench about 14” deep and fill the bottom 3” with rocks. Mix some native soil with whatever amendments are needed to build a sand-heavy blend with a modest amount of organic matter. Plant the corms at various depths as you fill the trench with soil. I’ve sunk ‘em down 8” with no problems. Hardier varieties such as ‘Violet Queen’ and ‘Atom’, as well as many old heritage classics may help you gain an edge on the colder weather.

Glads will do well with a mulch covering the soil and a balanced fertilizer after emergence.

How's everyone doing? I think we are now past the worst of the summer heat but to be honest I was ready for fall weeks ago. We may like to complain about the weather but when you are out in the hot burning sun day after day I think it's justified. Congratulations on making it through the dog days! Labor Day is the traditional end of summer but you and I both know there will be weeks of beautiful - even hot - weather before we trade sunscreen and Gatorade for hoodies and Carhartts. But today, let's get out of the sun for a minute and do some shade gardening.

I'm a big fan of shade gardening, and the plants that thrive in shade and partial shade. I used to have an enormous Hosta collection but now that I am gardening in the country I had to scale back on those because they are basically expensive entrées for our hordes of deer. I keep a few favorites behind fences but out in the yard I have better luck with ferns. 

Lest you think that all ferns need daylong shade, I have quite a colony of Ostrich fern that do just fine in nearly full sun. In fact they were getting a little carried away so I had to take some of them out. Here they are happily crushing my baptisia.

You're going to need to provide supplemental water especially under big trees, but established ferns can be surprisingly drought tolerant. Maidenhair fern can be a little fussy but Autumn, Lady, Male and Cinnamon fern are all happy in part sun to full shade, which is also where you will find ME when it's 90° or better. And you should really try to have some Painted fern if at all possible. 

So let's take a break from summer heat and enjoy this word search puzzle created by our very own Jeff Good. (Answers here)

If there is one plant every landscape should have, it is the peony. This handsome perennial is long lived and easy to grow, given a site with at least half a day of sun and decently well-draining soil. They are stunning focal points in mixed beds, or as the backbone of a perennial border, and belong in any style of garden from farmhouse to contemporary. Once I saw a row of peonies in full bloom running up a long driveway. I almost went off the road. The hard part is choosing which ones to plant. 

Peonies come in three types. The first, and earliest to bloom, are the woody-stemmed tree peonies (P. suffruticosa). The second are the fully herbaceous garden peonies (P. lactiflora, officinalis, and others), and the third are the intersectional peonies that are basically a cross between the two. Today's post is about the garden peony, the best known and easiest to find.

Let's dive in! Peonies have been cultivated for thousand of years and that means there are thousands of cultivars to choose from. Colors range from the purest bright white, to ivory, coral, pink - allllll the shades of pink - into fuchsia and finally, red. No matter which colors you choose, they all go together, so feel free to mix it up. The proper planting depth is key to getting flowers, so be sure to get those eyes no more than 1.5 - 2" deep. 

Peonies also come in a variety of different flower forms. My favorites are the wide open Single and Japanese forms, with bright showy centers, followed by the Anemone type that have a contrasting center fringed by wide petals. Other forms are Double, Semi-double, and Bomb. Many cultivars are fragrant, too. The earliest blooming ones kick off the season in mid-May, and by planting different cultivars you can go until late June. 

You may have heard that peonies, once planted, do not like to be moved. It is true that they are happy to stay in your garden for decades, but they can be transplanted successfully if you - like me - decide to move and can't bear to leave them behind. I've had my 'Sea Shell' peony for a good thirty years and she's doing great in her new garden.

Here in SE lower Michigan we have an amazing resource in the Nichols Arboretum Peony Garden (Ann Arbor), which has a massive collection of herbaceous peony, many of which are heirloom varieties. It has to be seen to be believed! Admission is free and the prime time to visit begins around Memorial Day weekend. You'll come away with a burning desire to plant peonies everywhere you can get a shovel in the ground.

All good things in life come from a bulb, isn't that how the saying goes? Okay, maybe not, but that is certainly true with Lilium! Planted in the spring (or fall), and returning every year, lily bulbs come in many different colors, and sometimes have a speckled or brush stroke pattern.

Lilium (Garden lilies) begin blooming in late spring, beginning with the Asiatic hybrids, and the distinctive fragrance of Oriental lilies on a summer breeze is sheer delight. With a little planning one can have lily in bloom for much of the season.

At Christensen’s Plant Center, we carry many lilies. One favorite is the Asiatic hybrid ‘Matrix’. This dwarf variety will only get 16” tall, and is a vibrant red with an orange brush mark in the center. We also carry tried-and-true Oriental Lily ‘Casa Blanca’ which gets 3-4’ tall. The highly fragrant pure white blooms are perfect for a classic look.

This year, we’re excited to offer three new Lilium combination pots. We’re loving the Asiatic Pot Lily Looks™ ‘Patio Sunrise Combo’ featuring yellow, pink, and orange dwarf varieties (14-16”). This will give you a fun mix that is perfect for a patio planter or cut flower bouquet.

The second is Asiatic Pot Lily Looks™ ‘Bloom Extensions™ Orange’. Lily flowers, though stunning, are usually short lived, but with Bloom Extensions™, you could get over 6 weeks of color. Two orange-flowering varieties, carefully selected to harmonize, have been potted together. The flowering times are offset, giving a seamless show of color. This is a great way to extend the display in your client’s landscape. This is an ultra dwarf combo reaching only 12-14”.

The third is Asiatic Pot Lily Looks™ ‘Bloom Extensions™ ‘Red & Yellow’. This stunning pairing of the yellow and red-speckled ‘Tiny Nugget’ (early, 14”) and the deep red ‘Tiny Rocket’ (later, 16”) is a real showstopper.

All the Lily Looks™ varieties have been selected for massive flower production, a short, compact habit, and suitability for container growing. Quantities are limited, and the grower has sold out - don't miss these! 

Whether you are looking for something unique or classic, our selection of Lilium has just what you are looking for.
