I have purchased a lot of David Austin roses from Hortico in Canada. they're grafted on multiflora.

Palatine is also in Ontario. I'm not sure which DAs they have but I know they have some.

Palatine doesn't have DAs. They have a lot of good roses though.

I just checked on Hortico and saw one that I might like. I'm just astonished at the shipping costs though. It seems Id have to buy 3 more plants in order to make it worth the costs. Its rather prohibitive i would think

I live in Canada and also have the same zone as you Ianna. I find Austins to be pretty hardy up here. I haven't lost any established austins yet. I usually find them at Sheridan nurseries but they only have older varieties. One year I've found it at the Loblaws garden centers. There should be some local garden nurseries that do offer some varieties. The only problem with austins in Canada is that they don't have a lot of varieties available compared to Kordes for example. Most of the famous kordes roses are available up here and they are widely available as well. I do find that I tend to "gravitate" to Kordes in recent years. I will try to post some pics up later when the roses start blooming.

Jjpeace - true when the austins were rooted onto hardy stocks that I have described. That supplier (Pickering) using these root stocks closed down. The ones now being sold by botanus or other bc based nurseries do not use these stocks. They use Dr. Huey instead. those are just hardy only to zone 7. the Loblaws ones used to get from pickering I suspect or possibly now from Horticos. I've not seen Loblaws offering these blooms since Pickering's closure though. I have one such plant which is still alive today. that's why the multiflora rootstock is important.

I will try to visit Sheridans to see what they have.

If you try Hortico, let me know how it turns out. I personally wouldn't buy from them again but of course that's just me!
