This one has a tubular cup – unusual for my seedlings since I most often used pollen from ( Actaea x viridiflorus) 12 YYG-GGO – which has a small disc or bowl-shaped cup. As would be expected, the tag for this seedling has descended into the box of soil and I cannot find it. Before this year, I had flowered only one trumpet x virid. sdlng ((Mesquite, a 2Y-Y) – and this might be another one.
Under 75mm diameter.
