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
Rudbeckia (Black-Eyed Susan) - a genus of North American wildflowers known for their showy yellow coneflowers. Most species are perennial, but Rudbeckia. hirta and all the showy cultivars are biennial, growing only leaves and stems the first season and blooming the following year.

Preferred growing conditions
  • Plant in most soil types including clay. Rudbeckia prefers to be planted in a full to partial sun locations.
  • Mulch with common mulching materials except of moisture climates where plants should remain un-mulched.
  • Irrigate regularly the first growing season to establish the plants. Black Eyed Susan likes dry to moderately moist soil conditions and should be given weekly supplemental irrigation in arid Western climates. Rainfall is generally sufficient in moister eastern climates.
  • Deadheading will help to keep the plants blooming longer into the late summer. But leave the last flush of flowers on the plants to set seeds
  • Fertilize lightly in the fall with a half and half blend of Yum Yum Mix and good quality compost.
  • Special comments
  • Seeds are enjoyed by seed eating songbirds. Plants with seed heads should be left standing over the winter months. Cut back hard in early to mid-spring. Biennial Rudbeckia hirta should be selectively cut back to remove dead foliage in mid-spring to prepare the plants for flowering later in summer.
  • Rudbeckia generally don't need to be divided.
