It is one of the most light-demanding plants in the Onagraceae family; it is not suitable for indoor environments without intense artificial lighting.

Prefers soils rich in organic matter, fertile, and with good moisture retention. In water gardens, use clay substrate or heavy soil mixed with organic compost. The ideal pH ranges from 6.0 to 7.5. Avoid poor sandy soils, as the plant requires constant nutrients to sustain its rapid growth.
