Hoary Vervain (Verbena stricta) is a beautiful native wildflower, with blue-violet flowers blooming from the bottom up on tall flower spikes in mid-summer that attract bees and butterflies. Ovate leaves are covered with whitish hairs, giving the foliage a silvery color and soft texture. Will naturalize and spread easily by reseeding. The seeds are a favorite food for seed-eating songbirds.

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).
