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" tall x 30-36" wide. What an amazing groundcover! After planting it into my garden, I've marveled how this vigorous plant grows to form a silver-gray, evergreen blanket of fine textured foliage, cascading down the slope it's plant on. It blooms in late spring-early summer with sweetly fragrant pink flowers held just above the foliage. Extremely heat and cold tolerant, it's a choice groundcover for the West, from Tucson to Boise, Denver to Reno and beyond.

Planting Guides
Teucrium (Germander) is a huge family of perennials, herbs and shrubs found world-wide, with the highest concentration of species in the Mediterranean region of Europe and Northern Africa.

Preferred growing conditions:
  • Plant in sandy or gravel soils, although many species can adapt to well drained loam soils; avoid clay.
  • Most species are best positioned in a full sun location.
  • Mulch with gravel or pine needles in dry Western climates. Leave un-mulched in moister climates.
  • Water regularly the first growing season to establish the plant. Thereafter, only occasional deep watering is needed, when conditions are dry in the heat of summer.
  • Deadhead the flowers when blooming is finished. Groundcover Teucrium chaemadrys 'Prostratum,' when used as a lawn substitute, can be mowed to deadhead the flower spikes.
  • Fertilize lightly in the fall with Yum Yum Mix.
  • Special comments:
  • Many Teucrium species are evergreen and shouldn't be cut back in the spring. But in late fall, rake off brown tree leaves and other fall debris to keep plants clean and foliage healthy over the winter. In spring, winter killed tips can be sheared off.
  • Teucrium chaemadrys and T. chaemadrys 'Prostratum' are a zone more cold hardy in dry winter Western climates than in the moist Eastern US.
