The white or very pale pink blooms of calystegia macrostegia (false morning glory) are about 2 inches in diameter and have a pentagonal shape, formed of five fused, grooved petals around a pale yellow center. Flowers grow profusely, contrasting with the dark green foliage, and the plant can become very large, expanding both upwards and horizontally, so is often used in gardens to mask fences and walls. Underneath the flower are five thin sepals supported by smaller green bracts. The plant blooms most of the year, peaking in April and May, and is found mainly along the southern California coastline.
