Size Plant - 5" deep pot


4-6" tall x 12-15" wide. This incredible native wildflower has been a work in progress for chief horticulturist David Salman for many years. “I first found the original colony at the summit of Poncha Pass near Salida, Colorado on a drive from Denver back to Santa Fe. Here, growing on the roadside, was a huge group of plants with deep red colored seed heads. Thrilled by the display and pleased to find ripe seed, I gathered a paper lunch bag full. By the next spring, I had plants growing in several of my stock beds to test this new find and gather seed for future crops,” explained Salman.

Eriogonum umbellatum ‘Poncha Pass Red’ (Poncha Pass Red Sulfur Buckwheat) didn’t disappoint, as it has turned out to be a very durable, long-lived miniature shrub that blooms reliably every year. The bright yellow flower clusters in late spring ripen to dark red seed heads by late summer. And the native bees are thrilled to have such a wonderful nectar source. Exclusive.

USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
