Rosa roxburghii is on my must-grow list time after time.
The single flowers (hooray!), large and in pale pink (ugh), are the least of the appeal for me.
But by blooming, the bush shows that it's happy, which is its own satisfaction regardless of the aesthetics. For my money, this rose is essential for overall form.
It's a monster of a bush—even here at the Zone-6 bottom of its range—getting ten feet tall and fifteen wide. But the real value of that size is that it's achieved via canes that get as thick as saplings. And so the rose can be trained up into a small tree, as I've done here.

So-called "tree" roses aren't generally hardy this far North: the trunk is grafted onto the rootstock, and the bushy and blooming top portion is grafted onto the trunk. One portion or another always fails in a New England Winter.

A tree-rose form of Rosa roxburghii, though, is the same individual top to bottom, bloom to root. And the trunk gets thick enough (at least over time), that the tree can be truly self-supporting too. It's a unique talent in hardy roses.


The ferny leaves are a classy texture when the blooms are done.
The bush is once-blooming only—a plus for me but a disappointment for those of you who actually like pink.

I cut back any branches that grow too far outside the general globe, and I adjust the stake so that the entire structure doesn't topple in some now-that-global-warming-is-really-here freak blizzard or ice-storm. But in time, this tree-rose will be stake-free and on its own, proud and pretty.

I've planted mine in one of my street-side beds, which would never happen if the plant in question weren't a year-round asset. Look for it if you visit Rhode Island: Mine is the only Rosa roxburghii tree in the state.
