Butterfly Bush or Summer Lilac
Many colors in this mix. A fine semi-shrub that is loved by butterflies. Plants will bloom the first year with an early sowing. The flowers are somewhat like lilacs in shape and display. Plants grow 72-100 inches (100 in = 2.54 m) tall but will freeze off in the northern part of the country; and regrow new stems again in the spring. Plants are small shrubs in the south. Fast growing with silver white leaves and stems.
Zones (4)5-9, zone 4 with good winter cover - but will not survive every year.
Fine seed, do not cover, use F 70-80 F (80 °F = 26.7 °C), germination in 1-2 weeks. The germination is spread out over a few weeks. Sealing up in a Plastic bag helps very much. The seed is very small and when sowing be careful so that wind currents do not blow them away. ( Keep bag out of direct sun light).
