Plant
Dense-flowered Mullein
Verbascum densiflorumAlso known as Denseflower Mullein, High Mullein
Dense-flowered Mullein towers over dry pastures and disturbed soils, producing a thick, woolly spike crammed with bright yellow blossoms in its second year of growth. Its soft, felted leaves form a basal rosette during the first season that traps heat and conserves moisture in harsh, open habitats. Bees and other insect pollinators flock to the dense inflorescence, which unfolds flowers sequentially from bottom to top over several summer weeks.

Responsible observation
- Observation: Look for the characteristic winged stems where leaf bases extend down along the stalk.
