Eustoma, commonly known as lisianthus or prairie gentian,
Description
They are
Eustoma flowers are either single-flowered or double-flowered. Both types of flowers can be found in all ranges of the possible colors listed above.[3] They are usually 30–90 cm (1–3 ft) tall, although there are dwarf varieties that only grow up to 200 mm (8 in) in height.[4]
Taxonomy
Eustoma (YOO-sto-ma) is a small genus, containing only two or three species.[5]
The genus name Eustoma is a compound of the Greek prefix εὐ- (eu-), "good, well", and Greek στόμα (stóma), "mouth", hence "(having a) pleasing mouth", while the obsolete Lisianthus is a compound of λισσός (lissós), "smooth", and ἄνθος (ánthos), "flower".
Cultivation
Eustoma is a beautiful, high-end cut flower, but it is tricky to grow and requires some maintenance.[6] It has tiny seeds that must be sown on the surface, not buried,[3] and it must be planted in rich, well-drained soil and exposed to full sun. It must be kept moist but not overwatered: overwatering may result in the growth and development of fungal diseases.[6] Careful control of temperature is necessary to prevent rosetting[3] and cultivation under cover is recommended to prevent spotting on the petals.[7] 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.[6]
Eustoma russellianum is particularly popular and has a number of cultivars that are grown for the cut-flower market.
