Eriogonum umbellatum Poncha Pass Red
Poncha Pass Red Sulfur Buckwheat - 2014 Plant of the Year
Details4-6" 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.

The shrubs and trees we sell are 1-2 year-old seedlings. These young plants appreciate some extra attention during their first 3 years in your landscape.
Preferred growing conditions:
- Check each species soil preferences before planting. Some do well in clay while others do not.
- Mulch with common mulching materials. As they get larger (2 ft. or more in height), thicken the mulch layer to a depth of 2-3 inches.
- Even xeric (waterwise) species will establish better and grow more quickly when given regular irrigation during the first 3 years in the garden. As they begin to reach maturity, watering frequency can be reduced to a good deep soaking every 10 to 14 days during the heat of summer.
- Plant in full sun or part sun depending on plant preference.
- Dig a wide but shallow hole and enrich the soil with ample amounts of compost and Yum Yum. This will help them to grow and mature more quickly. Special comments:
- Most native shrubs and trees are highly recommended for providing wildlife habitat (nesting spots, fruit or seeds for songbirds and mammals, nectar for pollinators).
- They are excellent for use to grow as natural (un-sheared!) hedges along fences, property lines and driveways. They live for many years once established. Garden Care:
- Fertilize in the fall with Yum Yum Mix and good quality compost. This is most important during the first 3 years in the landscape. Established plants don't need to be fertilized (unless growth is stunted by extremely poor soils).
- Where browsing animals (rabbits, deer and others) are a problem, it is advisable to protect young plants with a wire cage. These can be removed after 3-4 years in the ground.
- Mulching is essential to maintain the soil moisture these woody plants need to establish their deep growing roots. Be sure and replenish the mulch in fall and summer to keep it sufficiently deep.

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).
