blackhaw
Ooh ooh. I have a question!
Hey, I like the name blackhaw just fine and it’s the only correct quiz answer, but could we just for fun devise an alternative name following the pattern we see for maple-leaved viburnum?
Oh, good idea! Since Viburnum acerifolium is named “maple-leaf viburnum” (after Acer meaning maple and folium, leaved), it would make sense to call Viburnum prunifolium “cherry-leaf viburnum” because Prunus is the cherry genus.
