Gardeners' Notes:


On Dec 10, 2010, tgwWhale from Casco, WI wrote:

This rose is pretty and red and quite hardy, as advertised, In Wisconsin I would get it through the winter by burying it in mulch.

I gave it a neutral rating because I really disliked the growth habit. It likes to send out a branch with a large cluster of flowers out on the end. The weight of the flowers would cause the branches to sag down to the ground, and if it rained, the water in all those flowers at the end of the branches would inevitably weight them down into the mud.

Also, in my garden it proved susceptible to black spot. So although it is a nice rose, I culled mine out after several years, and I give it a neutral rating.

I bought this rose this spring so it has yet to survive an icelandic winter in my garden - hoping it'll do well because the flowers are just beautiful.

I've grown this beautiful rose for nearly ten years in the worst kinds of winter weather, and hot humid summers. It has never failed to grow and bloom beautifully with minimal care. Knowing it was Canadian bred was a factor in buying it (due to harsh winters here). It has never had any type of winter protection and has withstood temperatures a low as -22F. A good choice for worry-free gardening.

A wonderful plant with lot of bright red blooms from June until heavy frost. In my garden, it is very resistant to black spot and powdery mildew. Lot of buds even when winter is nearing and very tough plant to survive. It dies back to the snow line but once pruned, it comes out very well. I have two of them and I intend to have more and the cuttings root very easily.

One of my favorite, always in bloom with beautiful red flowers. It does suffer some winter damage however but since it is grown on its own root and not grafted, after I prune it in the spring, it rebounds nicely.

Excellent clear red colour and good flower form. Seems to bloom from mid-June until heavily frosted. In my garden I've seen it covered in ice in the morning and still popping open buds in the warmer afternoon. Not a large bush but very tough. Not prone to blackspot in my garden.
