Planting Guides

Oenothera (Evening Primrose) - a huge genus of biennials and perennials native to the Western hemisphere. Flowers are in shades of yellow, pink and white. Pollinated primarily by hawk moths. Flowers open in the afternoon and close by late morning the next day.

Preferred growing conditions
  • Plant in low fertility ("lean") soil including dry clay, positioned in full sun. Mulch with gravel or not at all.
  • Water regularly the first growing season to establish the plant. Thereafter, infrequent but deep watering is all this plant needs.
  • Deadheading is not needed as these are naturally long blooming species. Fertilize lightly in the fall with Yum Yum Mix.
  • Special comments
  • Oenothera are tap rooted plants and does not like to be transplanted once established. Don't divide as they resent having their roots disturbed.
  • Leave standing over the winter and cut back hard, leaving 2 to 3 inches of stems above ground.
  • O. speciosa 'Rosea' is a showy everblooming species that can spread aggressively and should not be planted into areas where it's enthusiastic nature can be a problem. Deadheaded to reduce reseeding. Dig out suckering roots when spreading too wide.
  • Watch for flea beetles (small metallic green beetles) which can defoliate the plants in late spring/early summer.

      Comments about High Country Gardens Oenothera macrocarpa Dwarf Silver:

      We planted several along the top of a rock wall that had been back filled with pea gravel. To my surprise these took off and flowered all summer that first year. This will be their second summer and they are all happy and filling out beautifully! Again.... these were planted in straight pea gravel!

      Q & A

      Suggested Companion Plants:

      USDA Hardiness Planting Zones

      To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

      • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
      • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
