Yesterday morning, before the sun became too intense, I walked along a trail which runs along the north canyon slope overlooking Bisbee. This was a favorite haunt of mine during the summer of 2012, when I was living in a house just below that trail.
One of my goals yesterday was to see how the Pink-throated Morning Glories (Ipomoea longifolia) were doing after the recent rains. This species of morning glory is a true Chihuahuan desert plant. In Arizona it can only be seen in two southeast counties, yet another Mexican plant which has found its northern limit here in Cochise County.
Morning glories tend to have heart-shaped leaves and a propensity for climbing. This species has narrow strap-like leaves and it won’t climb more than a foot or two, even when opportunities present themselves. The plant doesn’t reveal that it is indeed related to Heavenly Blue and other Ipomoea species and cultivars until it flowers.
This photo shows one of this morning glory’s vines making its way across the crumbling Pinal Schist. Look carefully at the right-hand side of the image and you can see one of the buildings of Old Bisbee several hundred feet below.
Here is the morning sun highlighting another traveling shoot:
I’ll be in Nova Scotia by the time this plant flowers. Ah, well, I’d love to see the fresh blossoms again, but you can’t always get what you want, right? Here’s a photo I shot during the 2012 monsoon season, soon after I first encountered this bewitching species:
