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).

Details
3-4" x 6-7" wide. Aethionema grandiflorum (Persian Stonecress) covers itself from spring to summer with fragrant soft pink flowers held over evergreen, bright blue foliage. Unusual papery seed pods follow after, extending the season of interest. A neat grower that forms small mounds of compact stems, this wildflower is excellent for the hot summer garden as it will thrive in sunny, dry growing conditions once established. Great for a rock garden. Leave the seed heads to encourage re-seeding.

Planting Guides

Aethionema (Stonecress) is a genus of Old World perennials with evergreen foliage and fragrant pink flowers.
Preferred growing conditions:

  • Plant in a fast draining, infertile soil with full sun. Mulch with gravel.
  • Keep regularly watered for the first growing season to establish the roots. Infrequent but deep watering thereafter.
  • Deadhead after flowering to keep the foliage tidy.
  • Fertilize lightly in fall with Yum Yum Mix.

Special comments:

  • Evergreen foliage doesn't like to be cut back unless removing occasional winter killed branches.
