Hooker's Evening Primrose is a perennial herb native to the American continent, often growing in wet ditches where it proliferates. It forms a basal rosette the first year. The second year brings tall flower stalks with a long succession of pale yellow flowers that age to orangey-red. The flowers open in the evening, hence the common name. It can grow 3-6 ft or more tall. A great plant to lure birds and insects into the garden. This flower can be distinguished from other Evening Primroses by its reddish sepals and buds. Flowering: July-October.
