A spring-flowering European plant related to the anemones, with purple flowers and fern-like foliage.
Pulsatilla vulgaris, family Ranunculaceae.
These include California poppy, Jamaican dogwood, cramp bark and pasque flower....
From mid-June through July, you should see profuse wildflowers, from the dainty, lavender pasque flowers to penstemons in shades of blue and purple.
Now that I have acid soil, I dream of pasque flowers and pinks.
Origin
Late 16th century (as passeflower): from French passe-fleur. The change in spelling of the first word was due to association with archaic pasque 'Easter' (because of the plant's early flowering).
