Common Mullein

Type: Heirloom, Open-pollinated, Biennial
Packet size: 100 seeds

Verbascum thapsus. Common Mullein is a traditional heirloom herb known for its tall, impressive flower spikes and large, soft, silvery-green leaves. This hardy biennial produces a low-growing rosette of fuzzy leaves during its first year, followed by towering stalks of small, bright yellow flowers in its second year. Mature plants can reach 4–7 feet tall, creating a striking addition to herb gardens, cottage gardens, and naturalized landscapes.

Mullein has a long history of use in traditional herbal practices and is especially valued by gardeners interested in growing historical medicinal herbs. Its yellow flowers attract bees and other beneficial pollinators, while its drought tolerance makes it an excellent choice for sunny areas with well-drained soil.

Planting Tips:
Start mullein seeds indoors 6–8 weeks before the last expected frost or sow directly outdoors in spring after the danger of frost has passed. Mullein seeds require light for germination, so gently press seeds onto the soil surface without covering them. Keep the soil lightly moist until seedlings become established. Thin young plants to allow adequate room for their large leaves and tall flower stalks. Mullein prefers full sun and well-drained soil and becomes highly drought tolerant once established. Plants typically produce foliage during their first growing season and flower during their second year. Allow flower spikes to mature if collecting seeds for future planting.

🌱 Excellent for traditional herb gardens, cottage gardens, pollinator gardens, historical medicinal herb collections, drought-tolerant landscapes, and naturalized growing areas.
