though it is only marginally perennial in my area (zone 6), I have been using Verbena canadensis as an annual here. They are typically sold at a nominal price....they are perfect for the cascading wall effect.. they bloom heavily but aren't a single blanket of blooms... a single plant can spread nicely within a single year.. blooming continually until the fall... and they don't need to be tended at all. They will root down where the stems touch the soil, but are very easily to pull up after the fall or in the spring. And they come in a few color varieties.

A lot of roses suffer from winter kill, here in Canada. Even here in southern Ontario. I have to cover mine to get them to bloom the next year, since most roses only bloom on the previous year's growth. This would explain why pruning in the fall will also prevent bloom. I lay mine down on the ground in the fall and cover with burlap, anchored with rocks. I toss all the cleanup from the garden on top of that. In the spring I clean it up into the composter, uncover the roses and tie them back up. If I leave them, what is above the snow line is usuall dead in the spring from winterkill (freeze/thaw cycle). There are only a few roses hardy enough to survive Canadian winters without being covered.

Northspruce, thanks for pointing out these are hybrid teas, not true teas... no problem in pointing that out. The name Sunsprite does ring a bit of a bell for me... I went out today and looked and the bloom still has its petals, but maybe they will drop shortly. They do seem to fall cleanly from older flowers on the same plant. SCG, I planted these deep when first planted, and on a slant to maximize the amount of stem underground. The crowns are probably about 20 cm below soil level. Each winter I mulch with leaves or straw to about a foot or two depth (sorry for mixing imperial and metric) but the above ground parts usually die to soil level anyway. They grow back quickly from the stems and crown that are underground.

You don't. If the issue is the root stock has taken over and the budded variety you wanted and obtained to plant has died out, then you are left with a once-flowering climber. If you want it to flower the best possible, then you train it as you would any climber, bending the canes down to closer to the horizontal so it produces lateral growth along the canes which will then flower. If you don't want a climber or haven't the room for it, then you simply whack the heck out of it down to about the size you want, then it will flower NEXT year on the remaining growth. Or, wait for it to flower, then whack the devil out of it. Either way, you likely have a once-flowering climber and eventually you're either going to have to treat it like one, keep whacking it down to keep it a small plant or replace it with a new plant. These are Dr. Huey, the likely rose you have and are dealing with. Notice the tall growth above the one plant? All the others would have those, too, had they not been cut off. But, they WILL appear...sooner or later.
