Viper’s Bugloss Cultivation
Growing viper’s bugloss is easy. Just plant the seeds directly in the garden after all frost danger has passed in spring and you’ll have blooms in a few short months. Plant a few seeds every couple of weeks if you want blooms all summer long. You can also plant seeds in autumn for spring blooms. Viper’s bugloss thrives in full sun and nearly any dry, well-drained soil. Plant the seeds in a permanent location because viper’s bugloss has a long taproot that makes it extremely uncooperative when it comes to transplanting. To plant viper’s bugloss, sprinkle the seeds lightly on the soil, and then cover them with a very thin layer of fine soil or sand. Water lightly and keep the soil slightly moist until the seeds germinate, which usually takes two to three weeks. Thin the seedlings to allow about 18 inches (45 cm.) between each plant.
