  • circleLife cycle

    The life of Verbena hastata f. rosea, commonly known as Blue Vervain, begins with seed germination which occurs in late spring after the last frost, when the soil has warmed sufficiently. Seedlings emerge and establish a root system, followed by the growth of a rosette of leaves in the first year; during this vegetative stage, the plant stores energy for future flowering. In its second year and subsequent years, Blue Vervain sends up tall, erect flowering stems that can reach up to five feet in height. Mid to late summer marks the flowering stage, where small, rose-pink to purple flowers bloom in candelabra-like inflorescences, attracting pollinators such as bees and butterflies. After pollination by these insects, the flowers develop into small, nutlet-like fruits which contain seeds that are dispersed by wind, water, or animals. The plant completes its cycle when it dies back after frost in the fall, leaving seeds in the soil to begin the next generation.

      Late spring to early summer

    • Verbena hastata f. rosea, commonly known as Blue Vervain, is often propagated through seeds. The most popular method involves sowing seeds directly into the ground in the fall, allowing the winter cold to naturally stratify them, which aids in germination. Alternatively, for spring planting, the seeds can be stratified in the refrigerator for a period of 4 to 6 weeks before sowing. To do this, the seeds are mixed with a little moist sand and placed in a plastic bag in the refrigerator. After stratification, seeds are sown on the surface of a seed starting mix, as they need light to germinate, and kept at a temperature of around 70 degrees Fahrenheit (approximately 21 degrees Celsius), which typically leads to germination within two to four weeks. Once seedlings are large enough to handle, they can be pricked out into individual pots and grown on until they are large enough to be transplanted outdoors after the last frost of the season.
