did you harden them off to sunshine before you planted them out???

ken

Does look like it could be buttonbush.

Ken,

No need, I wintersowed...they've not spent a day inside, ever! They were out on a deck in full sun which I think they didn't like. Since I transplanted them into a shadier place...woodland, the 2 partially green ones have grown new leaves and they look very happy! The red leafed one is def. alive but may have gone dormant (?).

Thanks, Esh! I figured they were either Viburnum dentatum or buttons...buttons it is!

Did you sow any Cornus?

I was thinking Cornus as well though I've never grown them from seed
so I have nothing to compare with these.

They do look like cornus, don't they? I know you suggested dogwoods in another post, Flora...I may have sown some C.alternifolia....could they be? That would explain why they weren't happy in full sun!
