Tips on Growing Blue Vervain Plants

Blue vervain (Verbena hastata) is also known as American blue vervain or wild hyssop. The plant grows wild in nearly every part of the United States. However, this cold tolerant perennial doesn't do well in climates warmer than USDA plant hardiness zone 8.

Blue vervain is a traditional medicinal herb, with the roots, leaves or flowers used to treat conditions ranging from stomach aches, colds and fever to headaches, bruises and arthritis. Native Americans of the West Coast roasted the seeds and ground them into meal or flour.

In the garden, blue vervain plants attract bumblebees and other important pollinators and the seeds are a source of nutrients for songbirds. Blue vervain is also a good choice for a rain garden or a butterfly garden.

Growing Blue Vervain

Blue vervain performs best in full sunlight and moist, well-drained, moderately rich soil. Plant blue vervain seeds directly outdoors in late autumn. Cold temperatures break the dormancy of the seeds so they are ready to germinate in spring.

Cultivate the soil lightly. Sprinkle the seeds over the surface of the soil, then use a rake to cover the seeds no more than 1/8 inch deep. Water lightly.

Care of Blue Vervain

Keep the seeds moist until they germinate. Thereafter, one deep watering per week during warm weather is usually sufficient. Water deeply if the top 1 to 2 inches of soil feel dry to the touch. The soil shouldn't remain soggy, but it also shouldn't be allowed to become bone dry either.
