Callistemon RED ALERT™


Callistemon viminalis ‘KPS38’ Red Alert™ PP25,673

A compact seedling selection of C. ‘Kings Park Special’, this Australian bottlebrush was selected for its abundance of prominent and vivid red new growth which is present for approximately two months in spring and two month in autumn. Responds well to pruning so use for hedges or let it be and it will make a nice specimen in any low maintenance garden. Red Alert™ needs less pruning to establish a hedge and is relatively disease-free so it makes for a great low maintenance alternative to Photinia (“red tip”). Best in Zones 9-11.
