Moth mullein or verbascum blattaria is a biennial that belongs to the blattaria species. It grows to a height of 4 feet in full sun. The plants have pink, yellow or white flowers that bloom in mid-summer to early fall. The foliage is evergreen and creates interest in the garden year-round. Moth mullein should be protected from too much moisture and freezing temperatures.
Protect moth mullein from root rot by making sure there is no standing water in the planting bed. The biennial has average moisture needs but should not be kept too wet.
Water the plant when the soil is drying out, which should be every 2-3 days. It should not be over-watered or it may rot and die.
Buy mulch such as cedar mulch, straw or hay from a garden store or nursery in the fall. Leaves also work well.
Wait until the ground is cold to mulch the planting bed. This will protect the plants from the alternate freezing and thawing that occurs around wintertime. Ideally, wait until there is an inch or two or frost on the ground.
Add 4-6 inches of mulch to the crowns of the plants. Make sure the soil is still relatively moist as the ground freezes, to ensure successful winterizing.
