White Obedient Plant is an erect deciduous perennial, growing in sunny moist sites. The plants have square stems and alternate pairs of variable and often toothed leaves, almost stalk-less with white flowers mainly in summer. The flowers will remain in a new position if they are moved on the stalks. They multiply rapidly, so allow space for them to spread. They are easily divided and transplanted; it’s best to do so after a heavy rain.
