Official Lobelia Flower Seeds (Organic)

Lobelia seeds offer a distinctive and medicinally significant addition to herb gardens, pollinator patches, and native plant landscapes. Known botanically as Lobelia inflata and traditionally referred to as Indian Tobacco or Pukeweed, this species is native to central and eastern North America. It’s valued in traditional Western herbalism for its antispasmodic and purgative qualities, and is a fascinating option for gardeners interested in native medicinals.

These annual or biennial plants begin as low rosettes and produce small, pale blue and white flowers followed by characteristically inflated seed pods—an identifying trait that gives the species its name. When overwintered, Lobelia typically blooms in its second season but can also be grown as a spring annual with attentive care. It thrives in rich, moist soil and tolerates part to full sun with consistent moisture.

Seeds are light-dependent germinators and must be surface sown without covering. Press gently into the soil and maintain even moisture and light exposure until germination, which occurs in 7 to 21 days. Plants are compact and grow well in containers or beds when spaced 6 to 12 inches apart.
