Campsis grandiflora

Anyone else grow this? I started this from seed last year and it survived this past winter - which was pretty hard here in Montreal (no snow cover and cold temps).

References to it indicate it's only hardy to USDA zone 7 or so. I'm wondering if I have the hardier C. radicans instead, or if the plant is much hardier than commonly believed. I did have it mulched and it was in an area that has allowed me to overwinter plants that are not supposedly hardy to my area, so maybe I am just lucky?

Hi Bonnie, I've had two for several years. They are growing very fast this year but neither have yet to bloom, M

RE: Campsis grandiflora

Do yours have any above ground growth that survives the winter or does it die back to the ground? I'm just wondering if I should bury the vine as some people do with some roses...

Bonnie, sorry to be so long in answering. I left the season's growth as is and it took a long time to show any signs of life but when it leafed out it all was well, still no buds but I have heard it can take years in our cold climate to bloom...not exactly what the catalogue said...M

RE: Campsis grandiflora

You mean a catalogue misled you?!? :-) Heh - if I had a dollar for every time I bought something that turned out to be different than advertised, I'd be rich! Well, ok, maybe not rich, but still - it has happened a lot to me too :-)

Mine looked dead until sometime in mid June - I only knew it was still alive because when I popped it out of its pot I could see nice healthy roots. It's grown a lot though this year so I was wondering what to do with the vine. I think I'll cover the vine with a good thick layer of mulch, just in case. There's a big one at the Botanical Gardens here, so maybe it'll be ok. I have no idea how long they've had it but it's big enough to bloom. I don't know what they do with it in the winter though...
