I will be visiting a friend in Huntingtown MD next month and I want to bring some plants to share with her. I have looked up hardiness zones and come up with zones 7a, 7b, and also just plain old 7. I will be bringing old standbys like daylilies and iris but I also have tropicals that I would like to bring her. I'm interested in your experiences about overwintering some of these plants outside.
Cannas, hedychium gingers, Colocasia, crinum, maybe a basjoo banana one day. I've read that Ellen Bosanquet crinum is hardy there.
Any experiences are welcome and any help is not just limited to MD.
