About Lisianthus
Eustoma russellianum, commonly known as lisianthus or prairie gentian, is a herbaceous biennial or short-lived perennial plant prized for its beautiful bell-shaped or cup-shaped flowers. Its delicate and often double petals, available in a wide range of colors (white, pink, purple, blue, and bicolors), make it ideal for floral arrangements and as an ornamental plant in gardens or pots. They add a touch of elegance and sophistication wherever they are grown.
Native range

Care tips
It prefers full sun or light partial shade, especially in warm climates. It requires well-drained, slightly acidic to neutral soil, and regular watering to maintain consistent moisture without waterlogging. Avoid overwatering, as it is susceptible to root rot; allow the top layer of the substrate to dry out slightly between waterings. A common mistake is lack of support, as its stems can become long and slender, needing stakes to prevent them from bending.
