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).

Planting Guides

Eryngium (Sea Holly) is a genus of Old World perennials with attractive thistle-like flower bracts surrounding the round flowers. Highly attractive to honeybees and butterflies.
Preferred growing conditions:

  • Plant in a fast-draining, infertile soil with full sun. Avoid clay soils. 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 it will not extend the bloom season or bring the plants back into flower.
  • Fertilize lightly in the fall with a half and half blend of Yum Yum Mix and good quality compost.

Special comments:

  • Eryngium is a tap rooted plant and does not like to be transplanted once established.  Don't divide as tap rooted plants resent having their roots disturbed.
  • Seed heads are ornamental and attract seed-eating songbirds.
  • These are low care perennials that don't like rich soil or a lot of water; this makes the plants leggy and prone to flopping.
