Boehmeria tricuspis grows in bushy, 1- to 2-foot tall clumps of slender red stems and handsome, bright green leaves. Slender wands of rosy pink flowers appear in midsummer and remain to add interest into fall. It’s not the showiest perennial, but it’s interesting and unusual and I enjoy having it around. It grows best in partial to full shade with soil that’s on the moist side. Perennial; probably Zones 6 or 7 to 9. (Honestly, there just isn’t much information on the hardiness range, but I can report that it has been fully hardy here in my Zone 6/7, southeastern PA garden.)
My original seeds came with this species name from the now-closed Canadian seed company Gardens North many years ago. I have seen photos of the species with green stems and flowers, as well as some showing the red stems and reddish pink flowers that these seeds produce. (The latter are sometimes referred to as “red form.”) Photos of B. spicata plants also seem very similar to mine. I am sticking with the name I’m familiar with, though, at least for now.
Collected in mid to late September 2023. At least 15 seeds. Shipping to US addresses only.
