About Lisianthus
Eustoma exaltatum, commonly known as Lisianthus or 'Hoa cát tường', is an annual or biennial herbaceous plant admired for its elegant, bell-shaped flowers resembling roses. Its delicate petals, often with ruffled edges, come in a wide array of colors, including white, pink, purple, and bicolors, making it a popular choice for floral arrangements and cutting gardens. Its upright habit and abundant blooming make it ideal for enhancing pots on patios or as part of floral borders in sunny gardens.
Native range
Mexico and the southern United States
Care tips
For optimal growth, Eustoma requires a location with full sun or light partial shade and a well-draining substrate rich in organic matter, with a slightly acidic to neutral pH. Watering should be regular, keeping the soil moist but avoiding waterlogging, especially during flowering. It is crucial to avoid excessive moisture on the leaves and flowers to prevent fungal diseases; watering directly at the base is highly recommended. A common mistake is the lack of support, as its floral stems can become long and heavy, benefiting from staking to maintain their upright posture.
