Mullein generally requires winter dormancy before it can flower. Verbascum thapsus, is also known as woolly mullein, the great mullein,common mullein,Aaron se Staf (Afr) or Aaron’s Rod (Eng), is a species of mullein native to Europe, northern Africa, and Asia.
It is a hairy biennial plant that can grow to 2 m tall or more and has a deep tap root. Its small, yellow flowers are densely grouped on a tall stem, which grows from a large rosette of leaves. It grows in a wide variety of habitats, but prefers well-lit, disturbed soils, where it can appear soon after the ground receives light.
The plant produces a rosette of leaves in its first year of growth. The leaves are large, up to 50 cm long. The second-year plants normally produce a single unbranched stem, usually 1–2 m tall. The tall, pole-like stems end in a dense spike of flowers that can occupy up to half the stem length.
Mullein Medicinal Benefits
Mullein tea is a traditional treatment for respiratory problems, such as chest colds, bronchitis and asthma. Both the leaves and flowers contain mucilage, which is soothing to irritated membranes, and saponins, which make coughs more productive.

Growing Mullein
Indoor Sowing: Not Recommended.
Direct Sowing: Late Winter, Early Spring and Autumn.
- Sow Mullein seeds direct in late winter, early spring or autumn.
- Surface sow the seeds thinly into prepared soil.
- Just cover the seeds with a fine layer of soil or vermiculite.
- Keep moist.
- Germination takes place at 15-18°C.
- Prefers full sun in a moist well-drained soil.
- Offer mulch protection during winter.
- Fertilize if desired, but this may cause leaf growth at the expense of flower growth. Will self-seed freely.
- In the first year plants are low-growing rosettes of felt-like leaves. The whorl of leaves emerge from the root crown at the soil surface.
- The bluish gray-green, oblong to lanceolate leaves are densely covered in hairs.
- In the second year plants produce a flower stalk 5-10 feet tall. They bloom a few at a time throughout the summer, maturing on the stalk from the bottom to the top in successive spirals.
- Each individual flower opens before dawn and closes by mid-afternoon. The flowers attract a wide variety of insects – bees, flies, butterflies and other insects, but only short- and long-tongued bees are effective in cross‑pollination.
- Flowers are also autogamous, so self-pollination occurs at the end of the day if the flowers were not cross‑pollinated.
- After flowering the entire plant dies – there is no vegetative reproduction.
