Amsonia (incl. genus Rhazya) or Blue Dogstars are very long lived, easily grown perennials within the Dogstar family (Apocynaceae). They make a perennial rootstock from which emerge annual racemes with ornamental, terminal clusters of densely packed, small starflowers in blue shades. A beautiful, very drought resistant genus for almost any well drained soil in a sunny position.
Sow the quite large seeds flat in any rich, well drained soil, keep pots in a sheltered spot outside during winter. Transplant young roots to the garden as soon as leaves wither in late autumn.
All are USDA Climate Zone 6.
20 seeds per package, if not stated differently.
