This attractive perennial (in zones 5-8) grows tall, reaching 3-6 ft in height. In late summer, strong stems produce loose, flat topped sprays of bright, acid yellow flowers that stand out beautifully in the garden! Excellent cut flower as well! Prefers full sun. Flowers in second year.
Approx. 35 seeds/pkt. Seeds require cold stratification for germination to occur. Achieve this by either sowing indoors, placing in fridge for 2-4 weeks, then returning to warmth or direct sow outside 3-4 weeks before last frost to allow nature to do the cold stratification for you!
