‘Plum Cascade’ is a new variety of Heucherella. No surprise that it’s a trailer. The profuse starry flowers were a nice surprise, and they have kept coming for the last five months. I have it in half shade, planted in a metal manger type window ‘box’ with Carex and Selaginella. The three plants have co-existed well even in the hot weather. It’s worth deadheading the ‘Plum Cascade’ to keep it tidy and the flowers coming. Thankfully Heucherellas don’t seem to get the rust that tends to clobber my Heucheras.
