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).

Details
This beautiful native wildflower blooms with blue-purple flowers blooming from the bottom up on tall flower spikes in mid-summer. The plant has a wide native range across the US, found primarily in the East and Midwest. It is a larval host plant for the Common Buckeye Butterflies, and a good nectar source for native bees. Hoary vervain enjoys a full sun planting spot, is drought tolerant, and can grow in a wide range of soil types. It thrives in average, dry to medium, well-drained soils, and tolerates dry sandy soils. Hoary Vervain is relatively short-lived, but can easily grow from seed, and will spread by self-seeding; leave flowers after they’re done blooming to encourage re-seeding, or, remove spent flowers to prevent unwanted self-seeding. Plant it with Purple Coneflower (Echinacea), ‘Blonde Ambition’ Blue Grama Grass (Bouteloua), and Goldenrod (Solidago).
