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).

Growing Fleabane (Erigeron)

Erigeron is a widely distributed genus that can be found worldwide in dry mountainous and grassland areas. The greatest concentration of the species occurs in North America.

Preferred growing conditions:

  • Plant in "lean" sandy, gravelly or garden loam soils. Avoid clay. Place in full sun.
  • Mulching is beneficial in the arid Western US using crushed gravel, pine needles or other coarse, non-water absorbent mulch material.
  • Fleabane appreciates regular irrigation their first growing season to establish themselves. Infrequent deep watering is fine from the second growing season and beyond. They won't need much if any extra water in the Eastern US.
  • Fertilize lightly in fall with Yum Yum Mix/compost blend.

Special comments:

Deadheading is not needed. Some species are somewhat short-lived and plants should be encouraged to re-seed themselves by allowing the fluffy seed heads to ripen and disperse.
