Verbena plants, known for its brightly colored blossoms and fast growth, are sun-loving and drought tolerant, making them perfect for warmer climates. While you can buy started verbena plants in a garden store or nursery, growing them from seed may be gentler on your budget. Vernalize seeds by sowing them in pre-moistened, sterilized seed starting mix in trays. Place trays in plastic bags inside the refrigerator for 2 weeks. Then bring trays up to 18-25?C (65-75?F), and seeds will germinate in 14-90 days.
