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

Twinspur (Diascia) are a group of showy annual and perennial species native to southern Africa. Preferred growing conditions:

  • Plant in compost-enriched garden loam soil. Avoid clay. Diascia grows well in with full sun to partial shade conditions.
  • Mulching is beneficial using common mulch materials.
  • These plants like moderately moist soil and appreciate regular irrigation when conditions are hot and dry. They won't need much extra water in the Eastern US.
  • Fertilize lightly in fall with Yum Yum Mix/compost blend.
  • Special comments:

  • Deadheading will encourage extended blooming over the summer growing season. Cut back to just above the ground in early to mid-spring.
  • Diascia spread gently via underground stems and can be divided in the spring to control the plant spread and propagate additional plants.
