Dalea (Prairie Clover) & Psorothamnus

Prairie Clover within the two genera Dalea and Psorothamnus are beautiful, rarely cultivated herbaceous perennials with showy elongated, white, yellow or pinkish flower heads above ornamental, finely feathered leaves. They are native of meadows and Prairies in North America and are easily grown in any humus rich, well drained soil in a sunny spot.
Sow flat on any humus rich, well drained soil. Only slightly cover seeds with soil. As for most winter hardy perennials, seeds require a cooling period for several months before they germinate in late spring to early summer, thus during winter place pots outside in a protected spot. Carefully transplant to the open garden as soon as plants are strong enough.
All are USDA Climate Zone 6.
20 seeds per package.
