Verbascum (mullein) is another favorite for the perennial garden. Like many other varieties, 'Southern Charm' blooms the first year after seeding. In following years, expect bloom in the spring, a dormant period in summer where summers are hot, and a rebloom in the later summer and fall. A short-lived perennial, verbascum typically lives three years or maybe a bit more, and many types (but not 'Southern Charm') reseed. Tolerates poor, dry soil and prefers neutral to alkaline conditions.
