About Purple cestrum
Cestrum elegans, commonly known as crimson cestrum or red cestrum, is an ornamental evergreen or semi-deciduous shrub cherished for its drooping clusters of deep red to crimson tubular flowers. Its vibrant blooms attract hummingbirds and butterflies, making it ideal for borders, hedges, or as a standalone specimen in mild climates, or in pots on patios and terraces in colder regions where it can be protected during winter.
