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
Plant in fertile, compost-enriched well-drained soil in a sunny to light shade location in the spring once danger of frost has passed. Planted in the spring, they will usually flower in late summer. With a head start indoors, or if they overwinter, they may start flowering by early summer. Hardy in zones 8-10, Tuberose flowers best when the bulbs are lifted in the fall even where hardy, and stored to be re-planted in the spring. After flowers are spent and foliage is yellowed, simply dig the bulbs and dry them for 7-10 days. Store in a cool (50°F) location and re-plant after the danger of frost has passed in the spring. For earlier flowers in northern areas, start your Tuberose indoors for an early start to sweet fragrance and lovely flowers.
