Eustoma, a genus of three species in the family Gentianaceae, grows natively in warm regions of the Southern United States, Mexico, Caribbean and northern South America. Examples grow mostly in grassland and in areas of disturbed ground. These flowers are commonly known as Lisianthus flowers. They are herbaceous annuals, growing to 15 – 60 cm tall, with bluish green, slightly succulent leaves and large funnel-shaped flowers growing on long straight stems: Sometimes erect single stems, other times growing on branching stems that can rise to one metre tall.

The flowers can grow up to 5 cm across and can be found in a variety of colours. They have been found in all shades of pink, purple, white, and blue. In addition, some are bicoloured and some are occasionally found in yellow or carmine-red. Lisianthus flowers are either single-flowered or double-flowered, the latter often called "prairie roses". Both types of flowers can be found in all ranges of the possible colours listed above. Lisianthus flowers are tricky to grow and require some maintenance.

They have tiny seeds that must be sown on the surface, not buried, and they must be planted in rich, well-drained soil and exposed to full sun. They must be kept moist but not overwatered. Overwatering may result in the growth and development of fungal diseases. Lisianthus flowers will begin to bloom in early summer and some will continue to bloom throughout the later months of the summer.

When cut, Lisianthus flowers can last anywhere from two to three weeks in a vase. Eustoma russellianum is particularly popular and has a number of cultivars that are grown for the cut-flower market. The cultivated flower is also often known as Lisianthus, Texas Bluebell, Prairie Gentian,Tulip Gentian, or just Gentian, although the last name can cause confusion with the related Gentian plant genus. Eustoma is named after the Greek words eu, which means beautiful, and stoma, which means mouth. Lisianthus on the other hand comes from the Greek words lissos, meaning smooth, and anthos, which means flower.

  1. They are beautiful! I sometimes see them in arrangements here but not out in a garden that I know of.
