I live in Virginia Beach, VA and posted a while ago about my confederate jasmines surviving here. Here is the latest update: Madison is supposed to be more cold tolerant than the other varieties. For the past 6 or so years they have all grown happily outside in the ground. This winter (since my last post) the temps got very cold (down to the low teens with wind chill causing single digit "feel"). My Madison jasmines suffered tremendously. All of the leaves "burned" and for all practical purposes appear dead. Strangely, the "other" confederate jasmines fared much better. Although some got a few burned leaves, most show not a whole lot of damage at all and are now starting to show bloom growth. The only difference between the two varieties is the Madison was planted on the front of my house and the 10 or so others in the back. I'm stumped but think it perhaps had something to do with the direction of the wind.

Wayside Gardens says: Madison is easy to grow, but best in partial to full shade in moist, well-drained soil. Prune it annually to keep it within bounds and looking its best. Hardy zones 7-10; an excellent greenhouse subject further north.

The large windmill palms in the picture are in large black plastic nursery pots. I have strings of incandescent miniature lights taped around the pots, and then fiberglass roofing insulation, and finally plastic sheeting to keep the insulation dry. This set up prevents the soil in the pots from freezing, allowing the palms to stay outside during temperatures down into the single digits. If it gets colder than that, I move the pots under the eaves of the house and tent them. Once the cold snap passes, back out they go. About one out of three years they spend the whole winter outside. I have a waggie (Trachycarpus wagnerianus) planted on the other side of the house, and I use the lights and burlap to protect it when it needs it. The night jasmine spends the winter in the garage. It can freeze in there sometimes, but these have recovered from 26F. They get chopped back hard in spring. Cestrum parqui seems stem hardy down below 20F, and can come back from the roots from much, much lower. I planted one this spring to give it a whirl! Waggie Windmills. The one on the left is actually slightly taller than the one on the right, which sits on a block. The pergola with the hummingbird feeder is 8' tall.

Our above ground vines died - in Austin TX. Did the Madison star jasmine varietal do better?
