Double Knockout Roses kick Lantanas' butt!

So when we moved into our home, there was a lot of landscaping already in place, most of which appeared to have been there since the house was built.

This included a little patch of rambling dwarf lantanas.

I eventually discovered that these things die back in the winter to the point of extreme ugliness. They would need to be pruned back almost to the ground in the spring.

Oh, yes, and they give me a rash when they touch my forearms.

So I started looking for something to replace them. Something with pretty dark green foliage that would keep its looks in wintertime.

Something with a long blooming season, and a profusion bright, red flowers

Something that could handle soil that stays wet for along time after it rains, but wouldn't shrivel up if things got a bit dry.

Something that wouldn't catch some nasty plant disease and die while I wasn't looking.

I finally settled on some Double Knockout roses. They are not antiques, but they are bred to be tough, even in lousy clay soils, and since I can't raise this existing bed to a height that would be good for an antique rose, Double Knockouts seem to be the best option in the rose department. They are supposed to be resistant to blackspot (unlike the Martha Gonzales roses I previously considered for this same location), and also tolerant of a wide range of temperatures and soil conditions. Being more compact than their sister, the original Knockout rose, these were appropriate for the limited space I have in this particular bed.

They will require significant pruning eventually, to keep them down to the size I want, but from what I have read, and from what I am told, they can handle that, too.

Oh yes, and did I mention that they are suitable for places as cold as USDA zone 4? That means they can survive temperatures down to -30 degrees Farenheit! (Though they need protection below 20 degrees, according to Floridata).

And the flowers are beautiful.

Those lantanas are toast.
