Calylophus serrulatus is a native plant found in dry prairies and mesas in western North America, particularly in the Great Plains from Canada to Texas. It is a low, shrubby, woody-based perennial, typically growing from 6 to 18 inches tall. Narrow, lance-shaped, toothed leaves crowd the branched stems. Four-petaled, stalkless, yellow flowers around 1" wide bloom from mid-spring to mid-summer. The flowers give way to 1" long seed capsules. The flowers of this species do not just open in the evening, but are open for the entire day. Leaves of this interesting prairie plant line up with their edges facing the intense mid-day sun as an adaptive way of minimizing water loss.
Best grown in dry, gravelly or sandy, well-drained soils in full sun. This is a tap rooted plant that tolerates drought extremely well but can be difficult to transplant once established.

Spring Shipping:
Orders are shipped within 7-10 business days. We will email you if there are expected delays.
When you order plants from our nursery, you can expect them to arrive in the best possible condition. Our team carefully packs each order using sturdy, biodegradable packaging materials.
Your plants' appearance may vary depending on the season and their current growth stage. We may cut back the leafy growth of some plants to prepare them for shipment and transplanting.
5 Gallon and Up: Any plant purchased to ship over 5 Gallons will be shipped bare root. This means we will remove the plant from its original pot, remove the soil surrounding the roots, and wrap the roots with a biodegradable plastic bag. This reduces weight and the likelihood of damage during shipping.
Once your plants arrive, it is essential to plant them as soon as possible. This will help them rebound and thrive. If you cannot plant immediately, water regularly and keep the roots off heat-conducting surfaces.
Newly transplanted plants often require more water until their roots are well established. Plan to water them 1-3 times weekly for the first few months.
