Lagerstroemia speciosa, also known as the queen's flower or queen's crape myrtle and pride of India, is an Indian deciduous tropical tree with white to purple leaves and a red trunk. Its leaves are extracted or used as a tea for a number of purported health benefits including balancing blood sugar and treating diabetes, weight loss and for kidney health. It is an attractive and fairly easy to care for tree, but will only thrive in very hot climates.
Plant the queen's flower in the right part of Texas. Langerstroemia speciosa is only suitable for USDA Plant Hardiness zones 9b and up. That means that it will grow best in the southernmost areas of Texas such as Brownsville and Fort Pierce.
Select an appropriate site for the seed. Queen flowers grow up to 60 feet high and spread up to 40 feet wide, according to the University of Florida, and require a lawn which is at least 4 to 6 feet wide. Plant Langerstroemia in full sun with well-drained soil that does not have high salt content.
Bury the seed under a thin layer of soil and water. Keep the soil damp, but not water-logged.
Fertilize when you plant it and regularly thereafter with a tree fertilizer.
Prune the lower branches if the tree starts to block the sidewalk, driveway or other areas. This will allow people and vehicles to get back and strengthen the tree.
