A compact variety with short, well branched spikes of violet-purple blooms with dark purple anthers, rising from a tight rosette of green leaves; the smaller size makes it perfect for containers; deadheading encourages new blooms
Sugar Plum Mullein has masses of beautiful spikes of violet flowers with plum purple eyes 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 oval leaves remain dark green in color throughout the season. The fruit is not ornamentally significant.

Planting & Growing
Sugar Plum Mullein will grow to be about 10 inches tall at maturity extending to 15 inches tall with the flowers, with a spread of 12 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 8 inches apart. Its foliage tends to remain low and dense right to the ground. 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 variety tends to self-seed and will thereby endure for years in the garden if allowed, although because it is a hybrid, the seedlings may not come true to type.
This plant should only be grown in full sunlight. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. 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 particular variety is an interspecific hybrid. 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.
