Verbena hastata -- (Blue Vervain)
 |
This verbena grows into a large clump 4-5 feet tall. It has stiff erect stems, lance shapes foliage and a spiky candelabrum of flowers. The flowers may not be as large as the garden varieties of verbena but they are abundant and bloom for a very long time during the summer months. The tiny tubular shaped blossoms grow in whorls up the pencil shaped spikes and are a treat for bees and butterflies. |
