Boneset is a native wildflower with deep historical roots in traditional herbalism, prized for its airy clusters of small white flowers that bloom throughout summer. This hardy perennial thrives in zones 3 and beyond, reaching 3 to 6 feet tall depending on growing conditions, and flowers reliably from June through August. It's a water-loving plant that doesn't demand fussy care, instead rewarding you with abundant blooms that draw pollinators year after year while shrugging off deer pressure entirely.

Boneset flowers arrive in dense, clustered panicles of tiny white blooms that seem to float above the foliage, creating an ethereal quality in the garden from early summer onward. The plant's deer resistance and strong pollinator magnetism make it a reliable workhorse for naturalistic gardens and meadow plantings. Its love of moisture means it thrives in spots where other perennials struggle, turning potentially difficult wet areas into vibrant wildlife habitat.
Boneset has a long tradition of use in herbal preparations, particularly infusions and teas made from the dried leaves and flowering tops. The plant is typically harvested during or just after its blooming period when the aerial parts are at peak potency.
No timeline data available yet for this variety.
Start seeds indoors about 3 weeks before your last frost date by mixing seeds with a moistened starting medium, sealing in a plastic bag, and refrigerating for 30 days. Check periodically to maintain moisture without oversaturation. After the cold stratification period, sow into a warm greenhouse or indoor location. Keep the medium lightly moist until seedlings are well established, then transplant once they've developed true leaves.
Transplant hardened-off seedlings outdoors after the last frost date into consistently moist soil in full sun. Space plants 12 inches apart, allowing room for their mature width of 3 to 4 feet. Water well after planting and maintain moisture until the plants are established.
Direct sow in fall or earliest spring by surface sowing and pressing seeds lightly into bare soil. You can also winter sow into pots in late fall. Keep the seedbed consistently moist until seedlings are well established.
Harvest the aerial parts (leaves and flowers) during or just after the blooming period from June through August when potency is highest. Cut stems above the foliage line using clean shears, gathering the flowering tops and upper leaves for drying.
