Obedient Plant - Physostegia Virginiana
Obedient Plant or False Dragonhead is a perennial that prefers a sunny to semi shaded position with well drained soil. These plants prefer hot dry summers. Each plant produces masses of bell shaped flowers on spikes at the end of summer, flowering for several weeks. Perfect for cottage gardens and looks wonderful in a naturalised landscape or meadow-type setting. It can be aggressive but easy to manage, deadhead which will encourage more blooms and also slow down the re-seeding. Young self seeded plants are easy to remove. Plants grow to approximately 60cm in height.
Excellent cut flower and the flowers can be bent in any direction. Harvest flowers and condition for at least two hours in cool water before using. Flowers will last between 7 and 14 days. Note, the flowers of Physostegia are highly sensitive to ethylene.
Seeds need a cold spell to break dormancy, if you live in a warmer area then store the seeds in the fridge for a minimum of 4 weeks before sowing. Sow seeds in a light potting mix and keep damp not wet. Plant out into the garden once the plants are around 10m in height and after the last frost.
