In gardening and landscaping, the mulleins are valued for their tall narrow stature and for flowering over a long period of time, even in dry soils.
Considered a noxious weed by most plant societies in North America, they are an invasive species that quickly adapts to choke out native flora, especially after fires.
Many cultivars are available, of which 'Gainsborough','Letitia', 'Pink Domino' and ‘Tropic Sun’ have gained the Royal Horticultural Society's Award of Garden Merit.

Since the year 2000, a number of new hybrid cultivars have come out that have increased flower size, shorter heights, and a tendency to be longer-lived plants.
A number have new colors for this genus.
Many mulleins are raised from seed, including both the short-lived perennial and biennial types.
