Ipomoea platense This is a nice, young specimen. They can obtain massive proportions in the wild. It just started flowering the first week of July. The individual flowers are rather short-lived (1-2 days), but there are many buds, and I am rewarded with new flowers nearly every day. If given room in a relatively large container, it will grow quickly. The large, tuberous, root system and caudex often displayed in bonsai shows is buried, for the most part. Raising this plant too early will stunt its growth. I've given it a rich, organic mix, however, well-draining to induce growth over the summer. I've also let the vines go where they want, without pruning. The vines do have the ability to climb, but are relatively poor climbers, hanging on loosely, even when given something to climb onto.
