Sowing: Direct sow in late fall, pressing into the surface of the soil. For spring planting, mix the purpletop vervain seeds with moist sand and store in the refrigerator for 30 days before planting. Keep the soil lightly moist until germination, which usually takes place within 14-30 days.

Growing: Water seedlings regularly until they become established. Though they flourish with occasional watering in especially dry weather, mature plants tolerate some drought in addition to growing in poor soil. Deadhead to prolong blooming. This plant may self-seed to the point of weediness, and is extremely attractive to butterflies and bees. It makes an excellent choice for a border plant.

Harvesting: For cut flowers, choose stems with flowers that have just opened. Strip the foliage that will fall below the water level, and place in water immediately.

Seed Storage: As soon as the flowers fade, watch the seed heads carefully since the tiny seed can easily blow away in the wind. Shake the seed heads over a container to remove the ripe seed; repeat until all the seed has ripened. Store the cleaned purpletop vervain seed in a cool, dry place.
