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
1" tall x 18" wide, (cutting propagated), Native to the Pyrenees of southern Europe, Paronychia is a tough-as-nails groundcover that very closely resembles Creeping Thyme. However, we have found it to be much more xeric. It is resistant to fungal diseases of the stems and foliage and is very tolerant of dry winter conditions. As such, we are recommending it as a replacement for white-flowered thyme. Blooming in late spring, the flowers are insignificant, but the white bracts light up the plant for several months. Can tolerate occasional foot traffic

Planting Guides
Paronychia (Nailwort) - A low growing groundcover native to limestone areas of the Pyrenees and Alp mountain ranges of Europe.

Preferred growing conditions
  • Plant in low fertility ("lean"), fast draining soil in a full sun location. Avoid clay. 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.
  • Fertilize lightly in the fall with Yum Yum Mix.
  • Special comments
  • Paronychia is an evergreen, mat forming plant that needs little pruning or clipping. The white flowers quickly form showy white seed heads which stay on the plant for many months. Old seed heads can be scratched loose and swept or blown off (with a leaf blower) in late summer.
