Blue Vervain (Verbena hastata) is a unique, eye-catching beauty in any garden. It grows quickly from seed and requires little care to maintain. Blue vervain will survive in dry sites, however the plant will be smaller and bear fewer flowers. Note that seeds are very small.
Growing Instructions
Wet and cold stratification required. Mix seeds with moist substrate (vermiculite, perlite or moss) and place in a plastic bag and refrigerate for 6-8 weeks. Sow seed at soil surface. Do not let seedling dry out while it is establishing.
OR
Sow directly outdoors in late fall to overwinter.
