More shots! I decided to take pics not only of those that have flowered, but also the ones which I know for sure are hybrids. Here goes:
Shots of 3 different looking D. tokaiensis x intermedia Easton, MA
D. spatulata 'Tamlin' x "capillaris Long Arm"
D. capillaris Long Arm" x intermedia Easton, MA: some have really elongate petioles, so a few are for sure hybrids.
D. "capillaris Long Arm" x natalensis: suspicious here, because plants aren't much different from the seed parent, but no swelling seed pods yet. Will update here if that changes
D. "capillaris Long Arm" x sp. Lantau Island
D. spatulata "white flower" x 'Tamlin': technically not a hybrid, but interesting growth form on this new variety
Got plenty of extras here, and probably need to thin the pot out: D. spatulata 'Tamlin' x sp. Lantau Island
Also need to thin this pot out: D. "capillaris Long Arm" x spatulata "white flower"
