Eustoma russellianum, is a species of flowering plant in the gentian family. Its previous binomial name was Eustoma grandiflorum. Common names include Texas bluebells, Texas bluebell, bluebell, showy prairie gentian, prairie gentian, and Lisianthus. There is a cultivar, 'Bolero Deep Blue'.
Texas bluebell is fairly disease-resistant and usually not prone to illnesses. Still, it can be affected by pests and diseases present in the surrounding area. Those problems are typically minor. For care, the plant requires moderate maintenance. It should be pruned regularly to preserve a tidy appearance and healthy growth. Fertilizing can also help encourage flowering. Texas bluebell is well suited for anyone with outdoor space, such as a garden or patio, and does not need extensive care experience. It may demand more attention when grown indoors.
How to keep Eustoma Russellianum.
Light
Texas bluebell thrives with abundant sunlight during the day and can tolerate somewhat milder light occasionally. Native to areas with long periods of sunshine, this plant’s growth may be slowed in overly shaded spots and it can become bleached if exposed to excessively intense light.
Temperature
In its natural habitat, texas bluebell thrives in temperatures of 68 to 95 °F (20 to 35 ℃). It is recommended to mimic these conditions for optimal growth.
Fertilizer
When most of a Texas bluebell's blooms have opened to their full size, resume fertilizing. At the time the blooms are at peak production, apply fertilizer every three to four weeks, as weather allows. Then, once the Texas bluebell begins to produce fewer new blooms, stop fertilizing; there is no reason to fertilize when the plant can no longer produce more blooms.
