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).

Growing Echinops (Globe Thistle) & Eryngium (Sea Holly)
Echinops (Globe Thistle) & Eryngium (Sea Holly) are very showy, Old World perennials grown for their attractive foliage and uniquely-shaped summer-blooming flowers. They are rich in nectar for feeding butterflies and bees of all types. Resistant to browsing rabbits and deer.

Preferred growing conditions:

  • Echinops and Eryngium grow well in most any type of soil including clay that doesn't sit wet.
  • Mulch with common mulching materials.
  • They are xeric (waterwise) and once established by the end of the second growing season do well with infrequent deep watering.
  • Plant in full sun.
  • Just a few handfuls of compost and Yum Yum Mix in the planting hole is enough. These plants don't like rich, compost-enhanced soils.
  • Special comments:

    • Deadheading will prolong bloom. Echinops will re-seed themselves so leave some seed heads on the plants.
    • Echinops plants are somewhat short-lived and should be replaced every three to four years or as they lose vigor.
    • Eryngium is longer lived when grown hard (not too much water and only a little fall fertilizer).

    Garden Care

    • Fertilize in the fall with Yum Yum Mix and good quality compost.
    • Leave plants standing and cut back hard in mid-spring. The large seeds are eagerly sought out by seed-eating songbirds.
    • Echinops can be divided in mid-spring. Eryngium is a tap rooted plant and does not like to be disturbed or moved.
