Description

A shell-pink native wildflower with sumptuous fragrance. Plants average 10 inches tall and 18 inches wide. They spread by a shallow root system of stolons and should be planted with care, as it will easily overtake your garden! This rugged beauty can handle an incredible amount of adversity from heat to drought; it is ideal for poor soil areas in need of a pollinator-friendly ground cover that can be allowed to spread and roam. Gorgeous on slopes and banks, rock walls, and meadows. Enjoy this easy-to-grow wildflower and please plant with caution and care.

Growing Tips: Perennial or biennial. Cold stratify 2-4 weeks, then sow indoors 4-6 weeks before the last frost. Barely cover, as light aids germination. Transplant outdoors after last spring frost. Often self sows.

When to Grow

Pink evening primrose is a stoloniferous perennial for zones 5 to 9, so choose its spot before you plant. Cold stratify the seed 2 to 4 weeks, then sow indoors 4 to 6 weeks before your last spring frost, leaving it on the surface and tapping it in lightly since light aids germination. Seed takes 20 to 45 days to sprout. Transplant after the last spring frost into full sun and well-draining soil, 12 to 18 inches apart; lean, poor ground and dry banks suit it far better than a rich bed, where it will run. Avoid over watering, and expect it to self sow.

How to Sow and Plant

  • Cold stratify seeds for 2-4 weeks.
  • Sow indoors 4-6 weeks before the last spring frost
  • Surface sow and lightly tap into the substrate.
  • Ideal soil temperature for germination is 60-70 F. A heat mat is not recommended.
