Hoary Vervain (Verbena stricta) is a gorgeous prairie native that is more compact and than its more popular relative Blue Vervain (Verbena hastata). Hoary vervain is the host plant of the Common Buckeye butterfly and its seeds are an important food source for small mammals and birds. While it self-seeds readily, hoary vervain does not compete well against more aggressive wildflower varieties and tall native grasses. Note, seeds are very small.
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.
Sow directly outdoors in late fall to overwinter.
