There are many Lagerstroemia hybrids and they vary in size and flower colour.
They are a deciduous shrub/tree, it will grow as a single trunked tree or a bushy shrub - it depends how you prune it.
They are grown for their brightly colour flowers which appear in abundance during mid to late summer. The flowers have five petals with an appearance of crushed tissue paper. The flowers are found in dense terminal panicles up to 20cm long on most branches.
An easy to grow small tree or shrub requiring well drained soil, and full sun, plant in a position that is sheltered from strong winds as these will destroy the delicate flowers.
The most popular group of hybrids are Lagerstroemia indica x L.fauriei with many new varieties that combine fabulous bloom colour with disease resistance.
