butterfly weed seeds

US Regions: Arid/Desert, Plains/Texas, Midwest, Northern, Northeast, Southeast

USDA Zones: 3, 4, 5, 6, 7, 8, 9, 10, 11

Sowing: In late fall, direct sow butterfly milkweed seeds just below the surface. Germination will take place in the spring, after the last frost. When the seedlings appear, thin to the strongest plant; seedlings usually do not survive transplanting, since they resent any disturbance of their roots. For spring planting, mix the seeds with moist sand and refrigerate for 30 days before direct sowing.

Bloom Season: Blooms Early Summer, Blooms Late Summer

Review By Mattia

Harvesting: This makes a striking cut flower. Because the stems contain no milky sap, these flowers tend to have a longer vase life than most milkweed varieties. Cut the stems long, choosing flowers that have just opened.

Butterfly Weed Seeds 6375. Bright, sun-loving plants are filled with brilliant orange flower clusters 10 cm (4″) across from June through to September. Mound shaped plants average 60 cm (24″) tall. Like its name suggests, this beautiful plant is a favourite of butterflies and other nectar loving insects. Butterfly Milkweed is a native Ontario perennial wildflower that is very heat and drought tolerant and an excellent choice for the low maintenance garden. Hardy to Zone 3.

125 seed/gram. Sow seed indoors in a soil-less mix in early March for late summer flowering in the first year. Growing medium temperature should be about 20 C (68 F). After germination, grow-on under lights at a cooler temperature of 15 C (60 F) before hardening off and planting out to a sunny site after the danger of frost has passed. Dormant fall seeding in mid October is also a good way to start not only this plant but many other perennials. Late fall seeding allows any dormant seed to be naturally stratified over the winter.
