How to grow Evening Primrose

Oenothera missouriensis

Tough plant that tolerates poor soils, including clay. Good candidate for xeriscaping (once established), borders, and rocks gardens. It may get aggressive if your soil is quite fertile, so it’s best in “problem areas”. It will develop better in looser soil. If starting from seed, will bloom second year.

It can take heat and humidity.

Pollinated by Sphinx Moth, which is actually in some amount of trouble due to native habitat being disturbed.

Growing Evening Primrose from seed
