Mullein

Verbascum thapsus

herb

Mullein (Verbascum thapsus) is a dramatic biennial that spends its first year as a ground-hugging rosette of large, pale, felted leaves so soft they were once used as lamp wicks and shoe liners. In its second year it sends up a single stout flower spike 4 to 8 ft tall, studded with five-petaled yellow flowers that open a few at a time from summer into fall and draw bees. It thrives on neglect in poor, dry, gravelly ground - roadsides, old fields, gravel - and self-sows freely from its dustlike seed. Gardeners grow it as an architectural specimen and harvest its leaves and flowers.

✅ Plant alongside

Good neighbors that attract beneficial insects or deter pests

• Echinacea — Shares the lean, sunny, well-drained conditions and the two make a tough low-water herb bed
• Yarrow — Another drought-hardy meadow herb that draws beneficial insects to the same dry border
• Calendula — An easy companion that fills in around the first-year rosette and brings pollinators

🛡️ Pest & disease prevention

Proactive ways to stop trouble before it starts — tap a name with an arrow for its full guide

• Mullein moth →

  The caterpillars chew the soft leaves - pick them off by hand, which is usually enough on a robust plant

• Aphids →

  Hose off the occasional colony on the flower spike; the felted leaves are rarely badly affected

• Spider mites →

  Appear only on drought-stressed plants in dust and are seldom a real problem on this tough herb

🌾 Harvest & storage

Harvest the broad leaves in the first or second year, taking them in the cooler part of the day and drying them flat in a single layer with good airflow, since the thick fuzzy leaves mold easily if crowded. Pick the yellow flowers in the second summer as they open, gathering them every few days over the long bloom season and drying them quickly. Both leaves and flowers are dried for tea; strain teas through cloth to catch the fine leaf hairs.

🥗 Nutrition & benefits

Mullein is grown as a traditional herbal-tea plant rather than a food: the dried leaves and flowers are steeped into a mild tea, and the bright flowers are sometimes infused in oil. It earns its place in the garden as much for its bold silver rosette, its towering flower spike, and the bees it feeds as for the dried leaves and flowers it provides.
