Purpletop Verbena has been found in such habitats as fields, roadsides, weedy meadows, and other disturbed areas. It also makes a stunning addition to the flower garden or border. It is fairly resistant to both deer and rabbits.
Brazilian Verbena seeds can be sown directly outdoors into prepared seedbeds. Late fall sowing is recommended as the Verbena seeds respond well to cold temperatures. If Purpletop Vervain seeds are planted in the spring, a cold treatment needs to be done before planting.
Dampen a paper towel, spread the Verbena seeds on the towel and carefully roll the towel up. Place the damp towel with the seeds in a ziploc bag and seal it. Place the bag with the flower seeds into the refrigerator for 4 weeks. After the cold treatment, the seeds can be started in the spring or even indoors.
