Description

Pouch Nemesia is a brightly colored annual that is native to southern Africa. They grow 6-12 inches tall and 6-12 inches wide. The long-lasting flowers come in assorted colors, including yellow, orange, pink, cream, red, mauve, and white. In mild temperatures, they can produce many flowers. There are a member of the Scrophulariaceae or figwort family.

There are 60 species of Nemesia in southern Africa, and they have been cultivated for many years as ornamentals. Pouch Nemesia is one of the most popular species. Cultivars of this plant are frequently grown as cool-weather annuals in the United States.

The genus name, Nemesia, comes from the Greek word "nemesion," which is the name of a similar plant. Nemesia is a symbol of friendship. Strumosa means "cushion-like swellings."

Pouch Nemesia performs best in full sun but appreciates part-shade in the afternoon, particularly during hot weather. They prefer cool to moderate temperatures. Soil requirements include well-drained, moist, loam, or sand with a neutral pH. Pinching the tips of the plant will promote bushy growth. It is best to cut back wilted flowers to stimulate flower production. The plant is propagated by its seeds that are easily dispersed by the wind.

The leaves are lance-shaped and have toothed margins. The flowers resemble an orchid. The upper lip has four lobes that form a fan, and the lower lip has two lobes. They may appear in racemes or solitary on the leaf axils. They come in a variety of colors, and some are bi-colored. They bloom from late spring to the first frost in mild climates. In hot climates, they are best grown in the spring or fall. The summer heat will result in die-back. They may also be a winter annual in frost-free areas.

This is an excellent brightly colored annual for borders, flower beds, containers, or hanging baskets. It may also be grown as a short-lived houseplant. The plant is hardy from zones 2 to 10.
