Showy Evening Primrose Flowers: Easy to Grow, Harvest, and Use

Showy Evening Primrose, or Oenothera speciosa, is a striking native American wildflower with four pink petals and yellow centers. This delicate-looking flower is also known as “Pink Ladies” and is surprisingly robust, growing and spreading rapidly without much care. You’ve probably seen these pink flowers many times when driving across the country, where their beauty as a mass planting is on full display. Their native range covers much of North America, from California to Florida and as far north as Pennsylvania.

Showy Evening Primrose is very easy to grow. Choose a sunny spot with well-draining, loose soil that you’ve prepared in advance for your seeds. Broadcast your seed and gently tamp it into the ground for good soil-to-seed contact, but only barely cover it. Light is necessary for germination, which typically occurs within 2-3 weeks. Once your seedlings come up, thin to space your plants about 12-18" apart.

Depending on your climate, Showy Evening Primrose can be grown either as an annual that is killed by cold every year, or a perennial that can survive winter and come back year after year. It also will easily self-sow in the same location year after year, so once you choose a spot for this low-maintenance plant, you won’t have to replant again anytime soon. Don’t let that discourage you though: the large pink flowers may seem fairly modest and delicate looking individually, but in a landscape, they are captivating. They also have a delightful fragrance!
