Vervain, Purple Top (Verbena bonariensis) - 100 Seeds
•American grown seeds
•Sow in Spring or Fall
•USDA Zones: 2-11
An excellent choice for a border plant, these clusters of deep lilac blossoms show off on tall, slender stems. This South American native perennial is easy to grow and is very attractive to butterflies such as Monarchs, Swallowtails, and Fritillaries.
Direct sow in late fall, pressing the seeds into the surface of the soil. For spring planting, mix the seed with moist sand and store it in the refrigerator for 30 days before planting. Keep the soil lightly moist until germination which usually occurs in 14-30 days. Water seedlings regularly until they become established. Mature plants tolerate some drought, but they will flourish with the occasional watering.
