I agree, Deb.
I just got to thinking about it again, and there are also a lot of diminutive plants chosen primarily for texture in the rock garden, too.
Pterocephalus depressus is a new one for me. Its leaves are also soft and somewhat feathery.
Pink Heron's Bill (Erodium 'William Bishop') , or really any of the perennial geraniums have touchable leaves, and some of them color up so very nicely in colder weather.
I missed getting a picture of it at its finest color this year, but Geranium (Geranium thunbergii 'Jester's Jacket') showed bright, lemon yellow leaves painted with pink to red streaks, and shot through with stunning chartreuse veins once the snow melted. Love it, too.
Finally, after several years of trying this plant, I think my
Prairie Smoke (Geum triflorum) has finally found its happy spot.
What's not to love about this plant?
Mine needs an after-winter trim yet, but it's getting a flower!
