These intensely colored moonflowers are heirloom morning glories - the desirable kind of morning glory. Convolvuluses all, they twine around whatever they can to climb toward the sun - which is what we so hate about bindweed as it scales and smothers other plants.
But these moonflowers, easily grown from seed, are mannerly annuals that die at first frost. My favorite is Ipomoea purpurea 'Grandpa Ott' with violet-blue, white-hearted flowers striped in deepest, glowing burgundy. A bee and butterfly-attractant, it needs sunshine, well-drained soil, and something to climb.
These are magical flowers that open overnight and close up in the afternoon sun, shown above on a misty morning growing in my Langley garden. Even their heart-shaped leaves are pretty - although they look uncomfortably akin to bindweed leaves. But gaze into the heart of a moonflower and you'll forget all about its problematic cousin..
