This xeric wildflower, native to the western Great Plains, blooms most of the summer with a profusion of bright yellow flowers. This is a tough colorful species that gently re-seeds itself when happy. Drought resistant/drought tolerant plant (xeric).
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).
6-8" tall x 15" wide (cutting propagated). A little known native from the short grass prairies of the western Great Plains. But not for long! A heavy bloomer from late spring through the summer, this tough plant will be the star of your xeriscape. Dwarf Sundrops likes a lean, well-drained soil and a good shearing before the growing season in late spring to keep it looking tidy and loaded with flowers. A fine companion plant for Nepeta and Penstemon.

Planting Guides
Tips On Growing Calylophus (Sundrops)
Calylophus (Sundrops) is a showy genus of native western species. Closely related to Oenothera, but these perennials are day bloomers.
Preferred growing conditions:
Plant in fast draining sandy, rocky or light loam soils. Some species (C. hartwegii) are fine with clay in arid climates.
All need full sun conditions.
Mulch with gravel or other coarse texted non-bark mulch.
Keep regularly watered for the first growing season to establish the roots. Thereafter, infrequent but deep watering is preferred.
Fertilize lightly in fall with Yum Yum Mix/compost blend.
Special comments:
Deadheading is not needed as these plants are naturally long blooming. Cut back hard in early to mid-spring to a height of 2 to 3 inches.
