TheGardenLady recevied these additional questions about Knockout roses.
I just heard about the knockout rose and think it will be perfect for my side patio. Two questions: The above picture? are those purple or pink? How does the Knockout do in partial shade?
There is no purple Knockout rose. They have single and double pink, single and double red, and have recently brought out a yellow rose plus they have a rainbow colored rose and a pale pink single rose. Check out their site.
TheGardenLady has the pink and the red Knockout roses . Though the company says they grow 3 to 4 ft high and 3 to 4 ft wide, mine are higher – 5 or 6 ft tall and and about 5ft wide. I pruned mine down this spring yet they grew back as tall. They bloomed their heads off this spring. And with all the rain we have had, the plants are very healthy with no rose diseases.
I just had the lower branches of trees pruned so that the roses would get more sunlight. Until then they were getting about 5 hours of morning sun. But the company says they can do well with as little as 4 hours of sunlight.
