Approximately 100 to 200 wild rose species grow naturally
around the world in the northern hemisphere. Most garden roses are complex
hybrids of these species. The Knockout rose series is the product of a breeding
program for increased disease resistance. As a result, this group of hybrids
does not require the typically heavy use of pesticides of traditional hybrid
roses. Knockout roses are available with flowers in various shades of pink.
Blush Knockout is a soft pink. It has a long season of bloom, in part because
it produces fruits rarely.
See this plant in the circle northwest of building 51.
Medium-sized shrub to about four or five feet tall.
Light: full sun
Water: drought tolerant when established, flowers best if irrigated
Soil: average garden soil, responds well to fertilizer
In general, roses grow well in a well-drained soil, in full
sun, in a spot with good air circulation. They flower on new growth.
Encouraging new growth with irrigation and fertilizer results in more flowers.
Keep the foliage as dry as possible to combat leaf diseases. Good air
circulation helps control fungal disease.
