Oregon Grape, Tall (Mahonia aquifolium) seeds

$5.95$44.10

Family: Barberry (Berberidaceae)

Hardy to Zones 4 to 9

Perennial evergreen shrub. Native to the Pacific Northwest of the United States. The leaves resemble holly, and in the spring the bright yellow, compound flowers emit delightful fragrance, and soak up the dew like a sponge.  Traditional usage (TWM): antibacterial, liver stimulant, water purification.  Source of the yellow alkaloid berberine.  Plant prefers loose, rocky and acid soils of hillsides and stream banks or the rich soil found under conifers.  We are offering cold stored seeds in order to help speed the typical multi-cycle germination of this species.  Sow anytime, for germination in warm soils.   Allow seedlings to grow for a year or more in nursery beds or in pots, then transplant to permanent location, 4 feet apart. Grows to 6 feet.

      Hello Anastacia,
      Thanks for contacting. For most seed packets that we sell, this can be done. Seed packets can be put in a lidded jar in the fridge for long storage. For Mahonia species specifically, no, we change these out yearly as they are short-lived. OK, one other small thing. When we sow seeds from our packets, we plant the entire packet at once in the right conditions. This gives maximum likelihood that a reasonable number of plants will result. Richo

  3. Question

    Frank Gagne

    Hi,
    I know in the description it says these seeds are “cold stored”. Would the seeds arrive dried? Or moist via being in soil?
    Thanks.

      These are from the fall harvest, cleaned and refrigerated fresh. they come in a packet like regular seeds–not packed in moist medium. r

  4. Question

    Megan Olmstead (verified owner)

    Put a packet of these into pots back in October or November. No sprouts yet… Should I give them another winter? Last winter rained so much, and although it wasn’t very cold we did have some freezing temps. I worry they rotted away or just want another trip around the sun?

      Hi Megan,
      Try to remember to request a free packet next time you order. I planted Oregon Grape (a different species, actually) in the fall and got seedlings in the early spring. That’s more what one would expect. Anything can happen.
