Care:

There isn’t much you need to do to successfully grow pink evening primrose. These plants are hardy, adaptable, and self-reliant. They require full sun and regular rainfall for the best blooms, but will otherwise preserve themselves by entering dormancy if they lack moisture.

Soil:

Plant pink evening primrose in loose, well-draining soil for best results. It does fine in rocky, sandy, or clay soil types. While many other flowering plant species thrive with rich soil, pink evening primrose actually prefers poor soil. This makes it a good option if you have an inhospitable spot in your garden or yard that you’d like to cultivate.

Temperature and Humidity:

Pink evening primrose has proven itself adaptable to various climates by naturalizing in 28 of the lower 48 states. This plant is hardy in USDA zones 4 to 9, and they tend to grow best in temperate to warm climates. They can withstand heat better than cold temperatures.

Fertilizer:

Given that pink evening primrose does best in poor soil, it's generally not advantageous to fertilize this plant species. The extra nutrients are of little value to this flower that seems to enjoy neglect more than nurturing.
