Similar to nearby observation but this one has normally shaped flowers. Flowers about an inch wide, in easily drained, sandy, soul. Vine sprawled along and up a fence near drainage ditch in same suburban yard as this observation:

This morning glory family plant seems to have a genetic abnormality because all of the flowers on it are split up one side and twisted. It was growing near other similar plants with more traditional, intact morning glory flowers. All the open flowers on this one had the split. At first I thought the large, totally open flower had been damaged because of the split up the side, but it seems too consistent to be individual damage. The flowers are about an inch wide. The vine is sprawled across land along a fence near a drainage ditch in front of a mowed but otherwise untended suburban front yard in sun most of the day.

Loose herb growing among other plants between mowed right of way and a fence line. Flowers are small, maybe 0.25-0.33 inches wide. Roots and most of plant are hidden under thicker plants out of sun but parts of plant get full Texas sun for at least half the day.

Plant growing in a mowed right-of-way along a small road in full sun. Plant was growing low to the ground; might get taller but flowered after mowing. Similar plants did better in slight shade near pencil cactus but I couldn’t approach those.

5 foot tall plant along roadside. It was shorter than the neighboring Giant Ragweeds and had more obvious flowers on slightly shorter and thicker spikes, but it might just be a late bloomer of the same species.
