Phonetic Spelling:RO-zuh

Genus:Rosa

Species:

Family:Rosaceae

Rosa Coral Knock Out® thrives in partial shade, setting it apart from most rose varieties. This distinctive type showcases a gradient of colors ranging from red and orange to peach, with hues becoming more vibrant in warmer temperatures and higher humidity—again, a rarity among roses. Complementing its beautiful blooms, the young foliage displays a striking bronze-red hue.

When it comes to watering, avoid overhead methods. Ensuring adequate air circulation is essential for fostering a robust and healthy plant while also helping to prevent diseases. During the summer, applying a layer of mulch around the base will help keep the roots cool, suppress weeds, and retain moisture.

To promote continuous blooming, regularly deadhead spent flowers.

The maintenance level for this plant is moderate. If pruning is necessary, it is best done from late winter to early spring.

Be aware that newly planted roses may be susceptible to damage from rabbits and deer.
