Oenothera lamarckiana

Known by the common names Evening Scented Primrose or Evening Primrose. It is easily recognizable as a tall plant with a central stalk covered with bright yellow 2.5 to 5 cm (1-2″) wide cup-shaped flowers which open late in the day. The seeds produced by the plant attract finches and other small birds. This specie performs well in average to dry soil with full sun to partial shade and is often one of the first plants to colonize bare open patches. Plants grow between 60-120 cm (2-4′) in height. Annual that re-seeds without becoming invasive.

How to Grow

Sow seed indoors in a soil-less mix Feb 1st but do not cover as light is required for germination. Germinate at 15 to 20C (60 to 70F) for 14 days. After germination, grow on under lights at the same temperature before hardening off and transplanting outdoors to a sunny spot. Outdoors, direct sow seed mid May.
