The queen flower tree is known by many names including queen's flower, queen's crape myrtle, pride of India and banaba. This deciduous tropical tree can reach up to 50 feet tall and is highly prized for its ornamental value. It has beautiful purplish-pink flowers that last all summer. Its leaves turn a striking shade of red-orange in the fall. The queen flower is easy to plant and grow and becomes quite drought tolerant after it is established.
Test the soil with a pH kit, available at most garden centers or a county extension office.
Dig a 5-foot square by 3-foot deep section of the soil over the planting area with a shovel. Turn the soil with a tiller. Add any amendments prescribed by the soil test. Turn the soil again and smooth it flat with a rake.
Dig a hole that is twice the diameter of the container that the queen flower sapling is in and just as deep.
Fill the hole with water and allow it to drain.
Remove the sapling from its container. Loosen its roots by gently pulling them away from the root ball with your hand. Prune away any roots that are broken, dead or diseased with pruning shears.
Plant the sapling in the hole so that it is at the same height in the hole that it was in its container. Do not pile soil higher than the soil mark on the sapling's trunk or cover the root ball with more than 1 inch of soil.
Water the sapling until the soil at the planting area is quite moist but not soaking. Water the soil to the depth of the root ball with a slow-running hose over the soil for best results. Keep the planting area moist until the queen flower establishes itself and produces new growth.
