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).

Hardy Plumbago (Ceratostigma plumbaginoides) is an outstanding, long-lived groundcover that slowly weaves itself into the garden fabric, creating large drifts of fall color. The deep blue flowers are numerous and long-lasting beginning in early fall. As the flowering finishes, the leaves begin a month-long change to a vivid mahogany red color. Plumbago is extremely adaptable, growing equally well in sun or shade, and thriving in a wide range of soil types. Hardy Plumbago (Leadwort) is slow to leaf out in the spring; be patient. It can tolerate occasional foot traffic. A flat of 32 plants will cover 48 square feet when planted together. 6-8" tall x 18" wide (cutting propagated).

Planting Guides
Plumbago (also commonly known as Leadwort) is an easy to grow groundcover well suited for average, medium and well-drained soils. Ceratostigma plumbaginoides is suited for full sun or part shade, but will perform best with afternoon shade in hot climates. Plumbago spreads by rhizomes and can be somewhat aggressive in optimal growing conditions. It can cause contact dermatitis if skin is exposed to vesicles. It is advisable to wear gloves when pruning the plant. The plant goes dormant in winter, leafing out in spring; in USDA zone 5 we recommend adding a winter mulch.
