Lagerstroemia 'JM1'

Colorama Scarlet crape myrtle

Colorama Scarlet crape myrtle (JM1), showing red flower clusters. Patent photograph.

Scarlet-red flowers give this vigorous crape myrtle a strong summer presence. Its eventual tree-sized proportions make it a better choice for spacious landscapes than narrow beds. Allow the branches to develop naturally rather than repeatedly cutting a large plant into a small space.
