Ornamental Features

Rosetta Mullein has masses of beautiful spikes of cherry red flowers with white anthers rising above the foliage from mid spring to mid summer, which are most effective when planted in groupings. The flowers are excellent for cutting. Its crinkled oval leaves remain dark green in colour throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

Rosetta Mullein is an herbaceous perennial with tall flower stalks held atop a low mound of foliage. Its relatively coarse texture can be used to stand it apart from other garden plants with finer foliage.

This plant will require occasional maintenance and upkeep, and should be cut back in late fall in preparation for winter. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Self-Seeding

Rosetta Mullein is recommended for the following landscape applications;

  • Mass Planting
  • General Garden Use
  • Naturalizing And Woodland Gardens

Planting & Growing

Rosetta Mullein will grow to be about 12 inches tall at maturity extending to 30 inches tall with the flowers, with a spread of 18 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 14 inches apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a fast rate, and tends to be biennial, meaning that it puts on vegetative growth the first year, flowers the second, and then dies. However, this species tends to self-seed and will thereby endure for years in the garden if allowed.

This plant should only be grown in full sunlight. It is very adaptable to both dry and moist locations, and should do just fine under typical garden conditions. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil pH, but grows best in poor soils. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
