Thermopsis chinensis 'Sunrise'
Chinese Bush Pea
Thermopsis chinensis is a star of the early spring garden emerging at the same time as daffodils and tulips, so it's very odd that this rather delightful plant is rarely known and seldom grown.
T. chinensis, has attractive greyish purple buds and soft yellow spires of lupin-like flowers that are tough enough to survive frost. The foliage on this species is clump forming but other members of this family, particularly T. montana are very invasive and difficult to eradicate.
T. chinensis is not invasive.
Thermompsis are native wild flowers of North America and eastern Asia.
They are fully hardy plants, coping down to -20ºC in habitats including the Rocky Mountains and Siberia.
Thermopsis are easy to grow in average, dry-to-medium, well-drained soils in full sun tolerating both heat and drought. While generally early to flower, after deadheading the foliage remains an attractive feature in the border.
Can be slow to establish, so have patience.
Well drained, fertile, dry
