Flowers form in terminal domed clusters up to 30 cm (12″) wide. A good wetland meadow plant as it tolerates constantly moist soils – also found along stream banks and marsh edges. Best in full sun but it will tolerate part shade. Perennial hardy to Zone 3.
How to Grow
4,400 seed/gram. Start seed indoors in a soil-less medium any time in late winter. Barely cover seed, moisten the growing medium and then place the container in a fridge or freezer for 3-4 weeks before bringing it back into the warmth. Keep at 15 C (60 F) for the 20 to 30 day (sometimes longer) germination period. After germination, grow on under lights at the same temperature then harden off and transplant outside to a sunny site with moist soil. Better yet, sow directly outdoors in mid-October in the site where it is to grow. This will allow dormant seed to be naturally stratified during the winter. This plant is slow growing and requires two years to flower when grown from seed.
