Two years ago I bought a Morning Glory Tree, I. fistulosa, at Barton Springs Nursery in Austin. That’s the only place I’ve ever seen one. I knew it would be risky in our zone 7b if we had a cold winter. Austin is a little over a 100 miles south of us and usually doesn’t have the low temperatures we do in a cold winter. So the plan was to put it in the shed before a freeze.
The tree is 5 feet tall now. The flowers look just like a morning glory vine blooms but are larger – 3″ to 5″ across. They open in the morning, but the whole thing looks droopy and sad in the midday sun.
I haven’t found much information on them. I’ve read that they are root hardy. I definitely hope that is true. It is a member of the sweet potato family and can reach 6′ in height. One source said it is multi-trunked and drought hardy. I’m not sure about the drought hardy part. It’s needs lots of water, but it is in a pot that is too small for it. So far it has one main trunk. We still have it tied to a pole for stability.The leaves are a different shape from the morning glory vine and are thicker, like tree leaves. I’ve read that they produce pods with seeds. Not yet.
When I step out on the back patio and see the tree across the yard, I love the sight of the large, white flowers greeting me in the morning.
