Verbena officinalis, commonly known as common vervain or simpler's joy, is a perennial herb in the family Verbenaceae. It is native to Europe but has been naturalized in many temperate regions around the world. The plant is known for its small, delicate purple flowers and has been used historically in herbal medicine. It typically enters a dormancy period during the winter months.
Verbena officinalis thrives in bright, direct sunlight and prefers moderate temperatures. It should be watered when the soil partially dries out, and it benefits from moderate humidity levels. Regular pruning helps maintain its shape and encourages new growth.

Pruning is essential for Verbena officinalis to maintain its shape and encourage new growth. Prune the plant in early spring before new growth begins and remove any dead or damaged stems. Regular deadheading of spent flowers will also promote continuous blooming.
