Trachelium caeruleum

Trachelium caeruleum (Purple umbrella flower). Like a lavender-blue “Queen Anne’s Lace,” this Mediterranean perennial bears large, dense domes of intricate flowers dotted with tiny white “pins.” Lightly violet scented, the 3-4” clusters on upright stems look lovely in any garden and it good for cut flowers. Easy to grow & vigorous. Blooms mid-Summer till Fall, just in time for the butterflies. Deadhead & give good drainage. To 3’ x 2’ & may self-sow.
This variety has leaves streaked with distinctive purple and black.
