Our Sulphur Buckwheat Collection showcases some of the very best xeric native shrubs for waterwise gardens. Sulphur Buckwheat (Eriogonum) are durable, showy plants with evergreen foliage and bright, long blooming flowers for months on end. Seed heads hold color for several months after the flowers have been pollinated, and offer food for birds in fall and winter. Both beautifully showy and beneficial, plant Sulphur Buckwheats for a foundation to your waterwise habitat or pollinator garden. Collection of 3 plants.
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).
Our Sulphur Buckwheat Collection provides essential habitat for beneficial insects, pollinators, and birds. Plant in full sun in lean rocky, sandy, dry loam and other fast-draining soils. Recommended companion plants include English Lavender (Lavandula), Phemeranthus (Fame Flower), and Nolina (Beargrass). Suitable for elevations over 7,000 feet.
The Sulphur Buckwheat Collection includes three plants:
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
