Exclusive. 'High Plains Yellow' Sundrops is a long blooming wildflower from the western Great Plains that withstands heat, drought and rugged growing conditions. 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).
4-6" tall x 12-15" wide. A new, long blooming wildflower introduction collected from the rugged, high dry plains of eastern NM, ‘High Plains Yellow’ Sundrops is well adapted to heat, cold, wind, and drought. This prairie native thrives in harsh conditions. Beginning in late spring, colorful, red speckled buds burst open into large, brilliant yellow flowers. It’s a superb companion plant for Lavender.

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.
