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).

18 - 24" tall x 24 to 30" wide. Leadplant (Amorpha canescens) that covers itself with hundreds of butterfly-attracting steel-blue flowers. This small-growing native shrub brings a welcome splash of color to the mid-summer garden. Our selected form of Amorpha canescens is grown from seed collected at an elevation of 7,500 ft.

Planting and Growing Amorpha (Leadplant)

Amorpha canescens (Leadplant) - a legume, this North American wildflower is deep rooted and adds nitrogen to the soil.

  • Plant in fast-draining, sandy or sandy-loam soils with full sun. Mulch with gravel or pine needles.
  • Water regularly the first growing season and infrequently but deeply after it's established.
  • Leave standing over the winter. Cut back hard in mid-spring.
  • No need to fertilize, as it is a legume and adds nitrogen to the soil naturally.
