CALYSTEGIA macrostegia subspecies cyclostegia. Mostly central coast, California. A real mouthful to say, through no fault of the plant's. It and many other native morning glories were recently reclassified and share the same burden. This is a lush, slender-stemmed vine, which scrambles overor throughany support. It has attractive dark green, roughly arrow-shaped leaves, which make a good cover. From late spring to fall, the plant is decorated by 2-3", trumpet-shaped blossoms, white overall and usually with contrasting pink ribs. My first selection, dubbed Candy Cane (which extends the name to six words), has large flowers with broad, deep pink bands. More recently I found one with almost uniformly pink flowers, dubbed Vicente for its location in the wild. Sun, most soils, moderate watering for best appearance. Both should be hardy to 15oF or less.
