How hardy are oleanders?
I went to a talk a couple of weeks ago by David Francko, author of "Palms won't grow here", a book about pushing the hardiness envelope and growing "tropical" plants like palms, bananas, and oleanders in the ground even in the north (OK, he was talking about zone 6). I am not sure I am going to change my garden right away, but I am interested in growing a few of these.
And when I was at Goldner Walsh (a good local nursery) for their auction and plant sale yesterday, I could not pass up a good bushy "Nerium oleander, hardy yellow" for less than half price. It will stay in the greenhouse over the winter of course, I wouldn't plant it now.
But I wonder who has experience with these outside in zone 6, maybe even zone 5? Are they hard to grow as container plants? Long blooming? Tell me about your oleanders, please. I'd love to see some pictures.
