Where most crape myrtles reach upward, 'Osage' arches and weeps, giving it a character distinctly its own among the Lagerstroemia hybrids. The pink flowers arrive in spring and carry through summer, and as the season closes the foliage turns a rich red before dropping — attractive fall color being something not every crape myrtle cultivar delivers reliably. Maturing between 12 and 18 feet, it occupies the middle range of its genus without overwhelming a small garden, and its drought tolerance makes it a sensible choice for the challenging dry conditions of urban sidewalk plantings and parking lot medians.

As a specimen it draws attention throughout the growing season, and its weeping habit gives it an informal quality that suits cottage-style plantings as much as more structured urban landscapes. It also does well in a large container for situations where ground planting is not an option. All pruning should be completed in winter or early spring, since 'Osage' blooms on new wood and cutting too late in the season removes the growth that would have flowered. A mulched root zone helps the plant hold moisture and weather the heat it needs to perform at its best.
