Trans-Pecos Morning-glory is probably most easily recognized by its long trumpet shaped scarlet flowers. These beautiful flowers attract hummingbirds in large numbers, and occasionally snakes will hide among the many leaves of these plants in an attempt to successfully catch a nice dinner. In fact, we found a Green Mohave Rattlesnake (Crotalus scutulatus) among some of the vines in the fall of 2012. The Green Mohave Rattlesnake (Crotalus scutulatus) is considered to be among the most dangerous! Ipomoea cristulata's beautiful leaves are highly variable, but they are usually either lobed, or highly dissected. The Trans-Pecos Morning-glory vines can be several feet long. Usually no longer than 10 feet, but we have seen some about 15 feet. It is an annual, to perennial herb/forb blooming in the summer and fall. The Arizona State Department of Agriculture showing the kind of great wisdom that they have, has placed this plant on their Arizona State-listed Noxious Weed (Prohibited Noxious Weed) list. They also list it as a rare native plant. Arizona could be one of the only states in the country where a state simultaneously lists a particular plant on both the rare plant and prohibited noxious weed list. It is shocking to think of any native plant species being declared a noxious weed. Until the Arizona State Department of Agriculture can view this situation from a factual basis and not just from a historic regulation, people are not supposed to cultivate these very special native plants. We are grateful they grow wild and we don't have to cultivate them! Anyway, we found several of these plants growing in many of the burned over areas in Yarnell, Arizona. about two months after the infamous Yarnell Forest Fire that destroyed many homes in Yarnell, including our own.
