Details6-8" 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.

Comments about High Country Gardens Calylophus serrulatus:
Planted this little guy a couple of years ago as filler/weed barrier in two gardens, one in full sun, the other shade in the morning and sun in the afternoon. Both spots are doing well and the first year the plant starting spreading as i expected - not gang busters, but slow and steady while maintaining a healthy look. The spreading was slower than I had hoped it would continue this year, but probably to the very unusually wet spring we had in Denver this year (2015). Still looks great though, even in a garden that received inches more moisture than it is designed for.

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).
