Knock Out Rose: Rosa chinensis

Knock out rose

This lovely bloom can grow up to 3 to 4 feet tall. It is so hardy you could forget they were planted and they would no doubt be able to survive. However, regular watering promotes a healthy abundance of blooms. Pruning is minimal but should be done in the spring time. Luckily they also do well in the heat and you can find flowers with twice the petals if you look for the double knock out rose variety.
