HO-HUM, ANOTHER NATIVE PLANT
In my quest to prove that not all native plants are crappy, I present this one from my woodland garden. Known to normal people as sweet shrub and to others as Carolina allspice, Calycanthus floridus beguiles us with the fruity, sweet fragrance of its brownish red to deep maroon blossoms that look like spiders splayed out on their backs. In the South, blossoms appear in April and May, but if you live in the frozen tundra of Wisconsin, Minnesota, the U.P., or Moscow, you’ll probably have to wait until June and July just like you wait for everything else.
Sweet shrub grows about 6 to 8 feet tall and wide. Actually, width is irrelevant as it spreads by suckers and thus will get as wide as you allow. I wouldn’t consider it invasive, though. Just cut off or pull up the suckers you don’t want – it’ll take maybe 10 minutes. Most people don’t give the foliage the credit it’s due. Glossy, deep green leaves turn bright yellow in autumn, providing a glowing understory beneath my oaks and hickories.
Not all sweet shrubs are sweet. Some have no fragrance at all. The flowers of mine smell of watermelon, but yours might smell like air. To ensure a heady perfume, buy one when it’s blooming so you can check. Or procure a named selection chosen for exquisite fragrance, such as ‘Athens’ (greenish-yellow flowers smell like Juicy-Fruit gum) or ‘Michael Lindsey’ (brownish-red blooms smell of strawberries). Google the names for online sources.
Success with sweet shrub is no mark of genius. It’s easy. The plant is not fussy about soil as long as it’s well-drained. It tolerates drought and blooms in either sun or shade. I have seen no pests, not even deer. If deer have gnawed yours to the ground, however, do me a favor. Keep it to yourself.
