Today for your delectation I am featuring the wonderful moonflower (Ipomoea alba). These are busy blooming right now and will continue to do so until frost. They have the most gorgeous twisted buds, which unfurl rather quickly at sunset. They stay open all night, the sphinx moths visit them. Then they collapse their sails of petals in the early morning.
It is worth the effort to go and visit some of the other participants in Photo hunt. You can find them here.
