Gumweed (Grindelia) (Grindelia integrifolia), packet of 30 seeds, organic

$3.95

Family:  Aster (Asteraceae)

Hardy to Zones 6 to 10

Bushy herbaceous perennial to 3 feet tall.  Native to the mountains and deserts of western North America.  This plant thrives roadside, in sandy areas seasonally flooded, in grasslands on dry slopes, in waste places, rock garden, or regular garden soil outside the reach of sprinkler. Sand mulch for best results. In colder zones, may be grown as an annual, or may become perennial, dying back to the root.  If your zone is too cold to support overwintering, be reassured that this is a reasonably dependable self-seeder.  In warmer zones, the plant will produce a thick, rubbery, perennial stem that may be crowned by a rosette of green leaves, and gives rise, in season, to more stems, followed by soft green cauldrons of resin giving way to the bright golden yellow flowers, flattened, about the size of quarters, which then in turn give way to the seedheads.  Traditional usage (TWM): asthma, poison oak and ivy. Plant prefers full sun and dryish, well-drained soils.  Sow seeds in spring.  Use fast-draining mix, or direct seed.  Barely cover seed with soil and tamp well, then keep warm, in the light and evenly moist until germination, which takes about three weeks, quicker or slower depending on soil temperature.  Individuate to pots and transplant, or thin to 1 to 2 feet apart.

  1. Question

    Michelle P

    I live in S Central TX – although this is in my zone for growing, trying to understand the soil it likes. I have basically beach sand (no not sandy loam). I don’t even have dandelions growing without creating a bed specific for them. How forgiving is this from this perspective?

      Hello Michelle,
      About as forgiving as a plant can get. I’ll never forget making a seed collection in Jemez in New Mexico, the plants growing in sand and gravel. Save the sandy loam for something else, these will grow along the driveway. PS we have really good seed on this this year.

  2. Question

    Kimmy

    I live in lower Michigan, Zone 5. We normally have plenty of hot days in July and August. Will Grindelia grown here likely produce enough resin to make a worthwhile medicine from? If so, roughly how many plants would be needed to create a pint or so of tincture each year? Thank you!

      Hi Kimmy,
      Yes, actually one can find wild grindelia growing throughout the US and it is easy to grow in gardens or even just in a spare bare bit of ground next to the driveway. You proabably would want to grow three plants. Pick the buds when they are in the milky stage and dry them before tincturing.

      Herbalists use the immature flower heads, dried. Check “Making Plant Medicine.”
