Speaking from Nova Scotia, I don't like to assure anyone that Palantine is a good bare-root rose supplier. It isn't! It's a fabulous bare-root rose supplier, but I'm trying to keep it secret so they don't sell out!!! I just may have let the cat out of the bag. LOL. I have been ordering from same for years. I order in November for April delivery. Always great stock, and tons of Kordes hardy roses.
In Canada, there is another great rose/plant nursery with locations in Ontario and British Columbia, namely Panamnurseries. Now they do not sell retail, however in Nova Scotia, "Wallymart" carries a lot of their roses, (usually the best varieties never make it here) and COSTCO offers a bunch of their roses/plants that we can order online, delivered bare-root right to my door, all in! Like cheap prices, great bare-root stock! eg. Here, 6 Carpet Roses for $79. That's very inexpensive delivered to our door. To buy some of their nicer roses, I work with a local nursery to order them in for me, and they give me a fair price. Panamnurseries does sell into the US. Through COSTCO, Panamnurseries also offers great collections of double lilacs, rhododendrums, and on an on. I would like to think that I am a "thrifty" plant purchaser, but in actual fact, I am almost out of control for a one man operation! LOL. Then of course, I still manage to pick up tons of plants from local nurseries and chains.
