Quite possibly the easiest rose I have . Blooms like crazy in my area not prone to blackspot or insects .

Hello, everyone: "Pink Knockout" grew and bloomed wonderfully its first year, with lots of flowers and orange hips. Since then, it's been the most blackspot-prone rose in my collection, has only one flush of bloom in early summer, and hasn't put out any new growth. I tried moving it to a full-sun location this spring (it's growing in a large pot). A potted specimen of "Benjamin Britten," near it, is doing fine, having shaken off a blackspot attack to set loads of new buds and clean foliage; "Mirandy," a 1945 hybrid tea in the same location, which got off to a shaky start in its first two years, is also disease-free at present and loaded with buds.

Well worth having if you love flowering shrubs. They are maintenance free and beautiful (until the Japanese Beetles arrive)!

Probably one of the easiest plants to grow, with virtually no upkeep. Not as tall as I like, but produces blooms perpetually.

I planted three of these last year, so far they have been very disease resistant.

I have a row of red and pink knockouts. They are very fast growing and I cut them back every year as they get as high at the top rail on the fence if I let them. They bloom in late May all of June and take a break in July only to really come back in August again and stay through September early October here.. Love them!! Not spraying is needed!!

I have the Pink Knockout Rose. I planted it just before it got really hot here (Many days over 115 and some over 120). It survived and flouished even when other established plants wilted in the heat. I was simply amazed! It made it through the whole hot summer so well I am ordering more.
