This is Anemone Decaen if not? it is Anemone St Bridgid. I planted both last autumn and am having a lovely mixed colour show.

i have japanese anemone which is in my raised border and west facing, does really well, they do like sun and partcial shade, good draining soil,

Looks like Anemone De Caen to me. Anemone blanda has a more star shaped flower. They are easily gorwn from 'corms' bought in autumn. I grow them in pots to begin with then plant out when they are in flower. they like moist soil, but not soggy in sun or dappled shade. They disappear under ground in about a months time.
These are not the same as Japanese anemone which are tall herbaceous plants with a tendency to spread for miles!

lol owdboggy mine not to avasive like some ,
apparently Decaen is best soaked for 24 hours before planting the corm,

I never soak mine Sanbaz. As I think in autumn the corm soaks up moisture in the ground. Mine have been flowering for about 6 weeks.

I had a feeling it was an anemone. I knew it wasn't Blanda as I have a lovely display of those at the mo and Owdboggy, my Japanese Anemones spread for miles too. They've even appeared in the lawn.
So I need to wait until autumn now to buy more Anemone de Caen. I only realised it wasn't there when I was looking through some old photos.
Thanks everyone.

yes thats sounds logical Drc, maybe its addvice for dryer countries,

Or summer planting SB?
