Knockout Rose Tree

August 13th, 2011

For many many years roses were hybridized for fragrance, or hybridized for color, or for size. Things like hardiness and disease resistance were not as much of a concern. It is only recently that gardeners in general started worrying more about these more functional attributes. The “Knock Out” brand of rose is one such newer line that professes to be hardy and disease resistant.
I’ve been hearing about these for years, but never bought one. Then I got an offer from Brighter Blooms for a free plant (one of the benefits of being a garden blogger, you get swag). In particular they had a rose tree, and that really appealed to me.
A standard form plant is one in which a bush or weeping style plant has been either pruned, or more likely grafted, onto a standard (a trunk). Almost all weeping cherry trees sold are in fact standard form grafts, where a normal cherry is grown to the desired height, a weeping bud is grafted on, and then once it is established any regular cherry growth is pruned off.
So a rose tree isn’t a rose that genetically grows like a tree, it is just a rose shrub of one type of rose that has been grafted onto a strong trunk-like cane of another rose.
In anycase, to me the benefit of a standard form rose tree, was that it was easy to find room for it. I stuck it between two very large hardy hibiscus plants. The standard form provides height which provides separation. Had it been a normal shrub rose it would have been crowded by the hibiscus, it would have needed more room. In fact, if it had been a normal shrub, I would not have had room in my garden for it, anywhere. I’m really low on space, but the standard form allowed me to sneak it in there.
