Three immediately come to mind, two of which are older cultivars:
'Black Eyed Stella'
'Black Eyed Stella'
'Crimson Pirate'
'Frans Hals'
These photos were all taken early in the blooming season and within a week or so were heavy-blooming clumps. 'Frans Hals' I would love to have a large bed of them, they really caught my eye every time I walked to the east side of the house. 'Crimson Pirate is my largest planting, seven or eight clumps, so they were visually striking as well since every clump was prolific.
'Black Eyed Stella'
