As we start slowing down into the fall season and get ready for winter, there was news from the Michigan Commission of Agriculture and Rural Development that needs consideration for next season. As you may have heard, they added several species<\/em><\/strong> to the Restricted Species list. This means that, effective January 1, 2028, it will be unlawful to introduce, import, sell, possess with intent to distribute, or intentionally propagate these species in Michigan<\/a>. While Christensen\u2019s can continue to obtain these plants for our customers in 2027, they will no longer be \u201cstocking items\u201d.<\/p>\n

Even with this year of reprieve, Christensen\u2019s suggests that our customers consider what can be used to replace the invasive plants because come 2028, they will no longer be sold or allowed to be imported into Michigan.<\/p>\n

The first to discuss is the Callery Pear (Pyrus calleryana)<\/em>, i.e. Cleveland and Bradford Pear.\u00a0 All of us know of the white flowers in the spring, so consider Amelanchier \u2018Cumulus\u2019<\/em><\/strong> as a suitable sub. Amelanchier \u2018Cumulus\u2019<\/strong> has white flowers at roughly the same time as Callery Pear. However, the flowers do not have the putrid smell of the pear and the branches tend to point upward giving it an upward look. \u00a0Amelanchier <\/strong>produce fall fruit, Juneberries, that tend to have birds eating them. The leaves start off green and turn orange and scarlet in the fall.<\/p>\n

Next let’s look at the ever-changing Japanese Barberry (Berberis thunbergii<\/em>). While there have been changes over the years producing sterile or non-seeding varieties, the way the Michigan law was written, they are still included on the restricted list. Varieties of Japanese Barberry currently found at Christensen’s include: ‘Crimson Pygmy’, ‘Rose Glow’, ‘Orange Rocket’ and the Sunjoy\u00ae Series.<\/p>\n

So, what can we use to sub for them? Any of the Iteas would be appropriate. Christensen\u2019s has carried these for a long time, but they are under-utilized. \u00a0Itea are a smaller plant, roughly 3′ to 5′ tall, with arching branches downward and white fragrant flowers. The leaves will start green then turn bright red or burgundy as fall approaches.<\/p>\n","protected":false},"excerpt":{"rendered":"

Last on our list is Buckthorn. Both glossy buckthorn and common buckthorn were added to the restricted list. However, of these, Christensen\u2019s has only carried Rhamnus 'Fineline' in recent years. Yes, it is different than what we all know as the scrub tree. But it is still in the same species. Cephalanthus occidentalis<\/em><\/strong>, buttonbush, is a great alternative.  Buttonbush has a round, white\/cream-colored flower that looks like a ball. This is also a great plant for both pollinators and songbirds to feast on later in the fall and winter months.<\/p><\/div>

As we navigate 2027 with these newly restricted plants, don\u2019t hesitate to discuss your projects with one of the sales staff at Christensen\u2019s. If the alternatives listed above don\u2019t work into your plans, they can help you find other options.<\/p><\/div>

Note: Property owners are not considered in violation if these species are already growing on their property or in adjacent waterways. The regulations primarily target the introduction, sale, transport, and intentional propagation of the plants.<\/em><\/a><\/p><\/div>","tve_custom_css":"@media (min-width: 300px){[data-css=\"tve-u-1a1829887ac\"] { max-width: 64.3%; }[data-css=\"tve-u-1a1829887ae\"] { max-width: 35.7%; }:not(#tve) [data-css=\"tve-u-1a18298e45a\"] { padding-bottom: 5px !important; margin-bottom: 0px !important; }[data-css=\"tve-u-1a1829905ec\"] { padding-top: 0px !important; padding-bottom: 5px !important; }[data-css=\"tve-u-1a1829fad43\"] { width: 300px; margin-top: 0px !important; --tve-border-width: 1px; border: 1px solid rgb(66, 66, 66); --tve-applied-border: 1px solid rgb(66, 66, 66); }:not(#tve) [data-css=\"tve-u-1a182a16a9d\"] { font-size: 14px !important; padding-bottom: 0px !important; margin-bottom: 0px !important; }:not(#tve) [data-css=\"tve-u-1a182a1f5be\"] { padding-bottom: 10px !important; margin-bottom: 0px !important; }[data-css=\"tve-u-1a182afb15d\"] { width: 683px; margin-top: 0px !important; --tve-border-width: 1px; border: 1px solid rgb(66, 66, 66); --tve-applied-border: 1px solid rgb(66, 66, 66); margin-bottom: 30px !important; }[data-css=\"tve-u-1a182afe4f8\"] { width: 683px; margin-top: 0px !important; --tve-border-width: 1px; border: 1px solid rgb(66, 66, 66); --tve-applied-border: 1px solid rgb(66, 66, 66); margin-bottom: 30px !important; }:not(#tve) [data-css=\"tve-u-1a182b044f8\"] { padding-bottom: 12px !important; margin-bottom: 0px !important; }:not(#tve) [data-css=\"tve-u-1a182b0ae49\"] { font-size: 14px !important; padding-bottom: 0px !important; margin-bottom: 0px !important; }:not(#tve) [data-css=\"tve-u-1a182b206d1\"] { font-size: 14px !important; padding-bottom: 0px !important; margin-bottom: 0px !important; }[data-css=\"tve-u-1a182b2d1ab\"] { padding-bottom: 0px !important; }[data-css=\"tve-u-1a182b3006c\"] { margin-top: 0px !important; margin-bottom: 0px !important; }[data-css=\"tve-u-1a182b310dd\"] { padding-top: 5px !important; padding-bottom: 5px !important; }[data-css=\"tve-u-1a182b56a4e\"] { width: 683px; margin-top: 10px !important; --tve-border-width: 1px; border: 1px solid rgb(66, 66, 66); --tve-applied-border: 1px solid rgb(66, 66, 66); }:not(#tve) [data-css=\"tve-u-1a182b5dab8\"] { font-size: 14px !important; padding-bottom: 0px !important; margin-bottom: 0px !important; }[data-css=\"tve-u-1a182b7361b\"] { width: 600px; }:not(#tve) [data-css=\"tve-u-1a182b7e68f\"] { padding-bottom: 12px !important; margin-bottom: 0px !important; }}","tve_user_custom_css":"","tve_globals":{"e":"1","font_cls":[]},"tcb2_ready":1,"tcb_editor_enabled":1,"tve_landing_page":"","_tve_header":"","_tve_footer":""},"categories":[131,18,66,13,82,10,22,129,6,126,96,128],"tags":[107],"class_list":["post-9894","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-2026-posts","category-about-us","category-about-you","category-business-tips","category-habitat","category-how-tos","category-landscaping","category-natives","category-plants","category-shrubs","category-technical-reference","category-trees","tag-dave-dermyer"],"_links":{"self":[{"href":"https:\/\/www.christensensplantcenter.com\/news\/wp-json\/wp\/v2\/posts\/9894","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.christensensplantcenter.com\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.christensensplantcenter.com\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.christensensplantcenter.com\/news\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/www.christensensplantcenter.com\/news\/wp-json\/wp\/v2\/comments?post=9894"}],"version-history":[{"count":10,"href":"https:\/\/www.christensensplantcenter.com\/news\/wp-json\/wp\/v2\/posts\/9894\/revisions"}],"predecessor-version":[{"id":9910,"href":"https:\/\/www.christensensplantcenter.com\/news\/wp-json\/wp\/v2\/posts\/9894\/revisions\/9910"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.christensensplantcenter.com\/news\/wp-json\/wp\/v2\/media\/9896"}],"wp:attachment":[{"href":"https:\/\/www.christensensplantcenter.com\/news\/wp-json\/wp\/v2\/media?parent=9894"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.christensensplantcenter.com\/news\/wp-json\/wp\/v2\/categories?post=9894"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.christensensplantcenter.com\/news\/wp-json\/wp\/v2\/tags?post=9894"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
