The Oenothera victorinii is one of the few flowers dedicated to Brother Marie-Victorin. Its flowers open at the end of the day and remain open all night. This makes it an important plant for some moths.

Sowing method : No pre-treatment necessary. Sow seeds when there is no risk of ground frost. Sow seeds on the surface without covering after sowing. These seeds are very small and need light to germinate. Seeds can be mixed with fine sand or talcum for a uniform sowing.
