Grindelia, Gumplant HGR-8160



Sought-after herb for asthma and other upper respiratory problems.

Rare in commerce, but easy to grow.

Three-foot plants are covered with yellow flowers.

In the center of each flower is a pool of balsamic resin, easily tinctured for medicinal use. Until all herbs were dropped from the official list of prescription drugs, this was prescribed for both asthma and poison oak/ivy.

Gumplant seems to interrupt histamine reactions and soothe overreactive systems. Likes full sun and good drainage. A rare and hard-to-find seed.

BOTANICAL NAME: Grindelia hirsutula


Soak seeds overnight and sow in damp but freely-draining medium in flats, or in place in a sunny, well-drained spot. Any garden soil that is not too acid or wet should do. When plants are 3" high, transplant to 18" apart. Doesn't require much care and is drought-resistant. However, the young plants need regular water to get established. Harvest flowers and top leaves when flowers are half-open and have a pool of resin in the center.

Incredibly hardy and drought tolerant
on 01/17/17 by Calvin Wilkins in Western Oregon

I grew this in my greenhouse, in raised beds with a very sandy loam. The greenhouse ended up in total neglect - zero water over the next year. The best we did was leave the doors open a little. Temps got easily in the 110 F range in the summer, it was like a cooker. Later that year, I went in to see if anything had survived. To my shock, both the Grindelia and Baikal Skullcap were in full growth and full bloom. They were probably better than if I had cared for them. The other thrivers/survivors were Darky parsley and regular alfalfa, which has a long taproot that could get down to water, I imagine. Fantastic plants.
