Overview
False Dragonhead (Physostegia virginiana) is a herbaceous perennial belonging to the mint family (Lamiaceae). It earned the nickname 'Obedient Plant' due to its flowers' tendency to stay in position when manually moved. The plant typically grows 2-4 feet tall and produces dense spikes of tubular flowers in shades of pink, white, or lavender from midsummer to early fall. Native to moist meadows and streambanks of North America, it has become popular in ornamental horticulture for its long blooming period and low maintenance requirements. The plant spreads via rhizomes and can form impressive colonies under favorable conditions, making it suitable for naturalistic plantings.
Product Features
The most distinctive feature of False Dragonhead is its symmetrical flower spikes that resemble snapdragons, arranged in perfect rows along the stem. Each individual flower is about 1 inch long with a two-lipped corolla. The leaves are lance-shaped with serrated edges, arranged oppositely on square stems characteristic of the mint family. This perennial is valued for its exceptional cold hardiness (USDA zones 3-9) and tolerance to both drought and occasional flooding once established. Modern cultivars offer improved garden performance, including 'Miss Manners' (pure white) and 'Vivid' (deep pink), which are less aggressive spreaders than the wild species.
Main Uses
False Dragonhead serves multiple purposes in designed landscapes. Its vertical flower spikes provide important structure in perennial borders and pair well with ornamental grasses or late-blooming asters. The flowers are excellent for cutting and last well in arrangements. In ecological landscaping, it's used in rain gardens and along pond edges where its tolerance for moist soil is advantageous. The nectar-rich flowers attract hummingbirds, butterflies, and bees, making it valuable for pollinator gardens. Some cultivars are specifically bred for container gardening due to their more compact growth habit.
Culture and Development
First documented by European botanists in the early 1700s, False Dragonhead was introduced to European gardens by 1732. Its botanical name Physostegia comes from Greek words meaning 'bladder' and 'cover', referring to the inflated calyx that covers the seed capsule. In the 20th century, plant breeders focused on developing more restrained cultivars suitable for formal gardens. The plant's cultural significance includes use in traditional medicine by some Native American tribes, though it's primarily grown as an ornamental today. Recent breeding emphasizes disease resistance and extended bloom periods.
B2B Procurement Guide
Commercial growers typically propagate False Dragonhead through division or tissue culture to maintain cultivar characteristics. For landscape contractors, bare-root plants or plug trays offer economical options for large installations, while container-grown specimens ensure immediate impact. Procurement considerations should include bloom time coordination with other perennials in the planting scheme. Verify phytosanitary certificates when importing plants internationally. For ecological projects, source native ecotypes from regional growers when possible. Bulk pricing typically applies for orders exceeding 100 plants, with discounts up to 30% for wholesale quantities.
