Thermopsis are care-free, long-lived perennials for the spring border. Resemble lupines with pea-like flowers. For added interest, flowers are followed with narrow, flattened seed pods.
Prefers moist, well-drained soils. Slow to emerge in spring. Shear established clumps back by 1/2 after flowering to produce more compact growth. Slow to recover after being disturbed, so division is not recommended. Cut top growth back after being blackened by frost.
Our plants are all grown in plantable fiber pots that grow incredibly vigorous plants, eliminate transplant shock, and are 100% biodegradable. They have tremendous advantages over plastic pots.
