I love Plant Delights and I would trust them for a good size plant but PD and the posters here said to plant them in spring so they will establish before winter. Also I read not to prune dead stalks till spring. Only an established plant would be hardy from 7b to 10 or so. As you see we are on the edge of the zone requirement and that makes me nervous because zones are based on average temperatures so my weather sometimes dips down similar to zone 7 and other times the temps seem more like zone 10! My challenge is to purchase plants that are at least hardy to zone 7b so that when it does dip down I will not loose plants, especially expensive ones! However purchasing zone 7 plants can be tricky too because most of them need a good cold spell which they probably will not get here. I would really like to plant one out in the ground and leave it but I see most people have them in pots. Maybe we can learn a few tricks here or maybe I will just experiment with a cheap plant to start off with. I guess it doesn't matter because we only dip way down about every ten years, but I sure do not want to loose a plant that is over 5 years old, that would drive me crazy. LOL.
