I have this one plant with no label and I thought it had seeded in a pot by itself, and it was Tellima.
Last autumn I planted it, and wondered about it because leaves were so hairy and different that Tellima leaves.
Now in early June it flowered and it is not Tellima, but can it be Tiarella polyphylla?
Many years ago I sowed T.polyphylla, but I thought that the plants all died the first winter outside (in pots).
Or what else do you suggest?
