Planting Guides

Growing Eriogonum (Buckwheat)
Eriogonum (Buckwheat) is a large genus of mostly Western North American wildflowers that are often shrub-like with woody stems. They are very important plants for habitat creation in our gardens.
Preferred growing conditions:

Preferred growing conditions:

  • Plant in "lean" sandy, gravelly or garden loam soils. Avoid clay. Place in full sun.
  • Mulching is beneficial in the arid Western US using crushed gravel, pine needles or other coarse, non-water absorbent mulch material.
  • Irrigate regularly during their first growing season to establish the plants. Infrequent, deep watering is fine from the second growing season and beyond. They won't need much, if any extra water in the Eastern US.
  • Fertilize lightly in fall with Yum Yum Mix/compost blend.

Special comments:

  • Don't deadhead. Many species have very showy seed heads that are lost when plants are deadheaded. Seeds are also utilized by many insects and animals for food.
  • Most species are actually shrub-like and should not be cut back or divided. A light top shear in early to mid-spring to remove the previous year's flowers stems is all that is needed

    Comments about High Country Gardens Eriogonum umbellatum Proliferum:

    It is one of the few plants that survive, thrive, and eventually bloom beautifully in spite of tough conditions of full sun, hard clay, and little watering during drought. Rabbits, deer, and slugs also leave it alone. It takes a few years to grow large (which is okay), and should be planted where it is not in danger of being stepped on, since the branches break easily.

      Comments about High Country Gardens Eriogonum umbellatum Proliferum:

      Don't let the product name fool you. While "beautiful" and buckwheat" may not seem to go together, in this case they do. These lovely little plants require no pampering and thrive outside my irrigation parameter in challenging high altitude conditions (9,000 ft in Telluride, CO). I get pretty yellow flowers in June, stunning bronze foliage in Mid-September. While my flowers are not as profuse as the plant pictured on the web, my plants are also left to fend entirely on their own after planting. I'm excited to be able to order more this year!

      Q & A

      Suggested Companion Plants:

      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).
