Physochlaina is a small genus of herbaceous perennials native in mountainous regions in eastern Asia. They make annual stems from a perennial rootstock, crowned by several showy lilac tubular flowers in late spring to early summer. It is easily grown in any humus rich, well drained soil in a sunny to partially shaded spot. Physochlaina will go summer dormant and resprout in following spring.
Sow seeds flat on any humus rich, well drained soil. Only slightly cover seeds and keep soil always moist from beneath. Place pots outside in a sunny and protected spot. As for most winter hardy perennials, seeds require a cooling period for several months before they germinate in late spring to early summer. Carefully transplant dormant rootstock to the garden from late summer to mid autumn.
All are USDA Climate Zone 6.
