Knock Out roses

Published 8:15 pm Saturday, April 15, 2017

Knock Out roses, introduced in 2000, are a commercial success, breaking all records for sales of a new rose. Knock Out roses are easy to grow and require no special care. They are the most disease-resistant rose on the market, have stunning flower power with a bloom cycle continuing from spring to first frost.

Names of the newest Knock Outs read like flavors at a snowball stand — Knock Out Pink, Blushing Knock Out, Rainbow Knock Out, Double Knock Out and Sunny Knock Out. Sunny is the newest, and aptly named with bright yellow buds that open to yellow petals that fade to light yellow and yellowish white.

If left unpruned, Knock Outs can easily reach a height of four feet with equal width. Periodic trims will keep them maintained to a smaller size. A once-a-year cut (to about 12-18 inches above the ground) in late winter is also recommended for maximum performance.
