They are native to warm regions of the southern United States, Mexico, Caribbean and northern South America.

[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".

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.

[6] Eustoma russellianum is particularly popular and has a number of cultivars that are grown for the cut-flower market.
