Plant id – Sundrops


Can you please help identify these flowers that grow every year in my backyard in Toronto? They are in full bloom on July 5 when this picture was taken. There is one flower on each stem. They are about 1.5 ft tall. In the fall, the leaves get lots of red on them. Thank you.


Thank you for your inquiry. From your photo and description it appears that the plant is question is Oenothera fruticosa commonly referred to as sundrops.

This perennial  grows best in  full sun – light shade in average, well drained soil. It is drought tolerant once established.

The plant usually begins blooming in early summer and continues until mid-late summer. You may wish to pinch or snip of the seedpods if you wish to prevent self sowing. Once the blooming period has ended you can trim back the flowering stalk to the basal rosette leaves.
