Culinary & Medicinal Herb Seeds
Gumweed, Coastal Gumweed
Asteraceae (Daisy Family)
Pacific Northwest of Canada and US
Will grow to about 3ft tall and wide with profuse gummy yellow daisy-like blooms through July until frost.
Full sun. Prefers well-drained sandy soil, but will grow in regular garden soil. Gumweed is a common native plant along our local beaches, sunny seasides, and sandy disturbed sites.
Seeds can be direct sown in fall or spring, or started in flats indoors in spring.
Plants are extremely drought tolerant. They will not tolerate soggy soil, especially in winter. Cut back plants in the fall.
The medicinal part of the plant is its sticky gum laden flower buds, which begin to form in late May but don't begin to open until late June or early July. The prime harvest time is just as the flowers being to open and when the gummy latex is visible on the flower buds. The leaf can also be used but is not as strong.
The buds have a warm energy and balsamy taste that is quite lovely, especially infused into honey.
Grindelia acts to relax the smooth muscles of the body (lungs and heart especially) and is useful in the treatment of asthma and bronchial conditions combined with nervousness and anxiety. Expectorant for dry unproductive coughs. Antimicrobial and diuretic for urinary tract infections.
Grindelia can also be prepared into a topical preparation that is healing to rashes, minor wounds, and itching. Great for relieving irritation from poison oak or poison ivy.
