Plains Yellow Primrose

The Story

Plant Bio

Oenothera serrulata, plains yellow sundrops, is a low taprooted perennial of the central North American prairies, six to eighteen inches high and about as wide. Clear yellow four-petalled flowers open along the stems through June and July above narrow, finely toothed leaves. It is still widely sold under its former name, Calylophus serrulatus.

The taproot is the thing to plan around: it makes the plant exceptionally drought tolerant once settled, and almost impossible to move afterwards. Plant it young, from a pot, straight into its final position. It thrives on dry gravelly ground where richer soil and regular watering would make it flop.

Uses & Benefits:

Clear yellow four-petalled flowers over narrow toothed foliage through early summer.

Holds dry, gravelly ground that needs no irrigation once established.

A prairie species whose open flowers are readily worked by bees.

Planting

How to Grow

Plant in full sun in dry, gravelly or sandy soil.
Choose the final position before planting; it resents moving.
Set young pot-grown plants rather than large divisions.
Water lightly through the first season only.
Skip feeding; lean soil keeps growth compact.
Cut back to the base after flowering finishes.

Pro Tip

Site it once and leave it; the taproot that makes it so drought-proof also makes an established plant nearly impossible to transplant.
