Mullein (Verbascum, Great Mullein, Common Mullein, Aaron's Rod, Cowboy Toilet Paper)

• Common Name: Mullein (Verbascum, Great Mullein, Common Mullein, Aaron's Rod, Cowboy Toilet Paper)
• Latin Name: Verbascum spp.
• Family Name: Scrophulariaceae

Now cultivated for the garden, Mullein contains rotenone, a natural insecticide, and coumarin, which can be broken down into dicoumarol, an anticoagulant whose derivatives are used in warfarin, so it should not be planted in or near the tortoise enclosure.

Although usually a wild flower, these plants are now often grown in the garden.
