Red evening primrose

<em> Oenothera versicolor</em>

Evening primroses are not such an unusual thing, but this highly variable species from Mexico is rarely encountered in prairie gardens.

Growing 45 to 60 centimeters (18-24 inches) tall, red evening primrose produces very showy flowers in shades of orange, peach, pink, coral, salmon, or yellow. Although it is a perennial from Mexico, it is not hardy through cold winters. It is extremely fast growing and makes a splendid annual on the Canadian prairies. It can be moved indoors during the winter months.

‘Sunset Boulevard’ is a cultivar of this species that is absolutely smashing. It is compact and heavy blooming, with larger flowers than the species. Blossom color ranges from orange through reddish orange to copper, aging to shades of peach, coral, and pink. It is outstanding in the garden and positively glows when it is backlit by sunshine.

The long, lance-shaped leaves often have maroon or bronze undertones, which complements the flowers. Perhaps the most curious thing about this species is that the flowers open in the morning and stay open throughout the day, closing in late afternoon or early evening. This plant is absolutely worth trying!
