This flower may act as a biennial or perennial depending on the conditions but will reseed and spread like an annual.

It is mainly seen as a full sun prairie plant but is also found in other low elevation areas.

The golden yellow flower is cup shaped and turns a darker reddish color as it fades.

True to its name it will bloom in the evening and then wither but more buds are always waiting to open throughout the long bloom period throughout summer and fall.

Hooker’s Evening Primrose can be found throughout the western United States and will grow in USDA zones 3-10.

This plant is very tolerant of wet situations and will become a fairly good-sized plant.

Plant Sun Drops where they will have ample space to grow.
