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
Linum (Flax) - a large family of wildflowers found throughout the temperate and sub-tropical regions of the world.

Preferred growing conditions
  • Plant in a fast draining, infertile soil with full sun. Avoid clay soils. Mulch with gravel or not at all.
  • Water regularly the first growing season to establish the plant. Thereafter, infrequent but deep watering is all this plant needs.
  • Deadheading is not needed, and re-seeding is encouraged.
  • Fertilize lightly in the fall with a half and half blend of Yum Yum Mix and good quality compost.
  • Special comments
    • Linum is a tap rooted plant and does not like to be transplanted or divided once established.
    • Plants can be short-lived (3 years, occasionally longer) and should be encouraged to re-seed themselves. Planting them in areas mulched with gravel is recommended.
    • Leave standing over the winter and cut back in early spring just above the rosette of new leaves around the crown.
