This plant has absolutely huge flowers, often close to 4 inches in diameter, which is somewhat unusual for a native prairie plant. It will also bloom nearly continuously from spring to late summer.

In our part of Texas, deer will munch on these plants if they can get to them. But I see them along the highways in certain areas and they seem to be doing fine there. They appear to be drought resistant, as they have survived years of extreme drought in southcentral Texas. Gorgeous wildflower!

The evening primrose is invasive. You might want to plant into a container in the ground to contain its spread. The root system is relatively shallow.
