Sensationally big 4-5” lavender-blue flower heads are produced lavishly over a long season – May to September – on this vigorous and fast perennial. Held atop 3’ stems and pretty foliage, the lightly scented, dense umbels are dotted with tiny white “pins”. Super landing pad and nectar source for butterflies and adored by bees. Long-lasting cut flowers galore! Rich, well-drained soil a must! Root hardy to 10-15°F. Self-sows!
