The moonflower belongs to the same family as the ever-popular, chartreuse-green potato vine that you see spilling out of many summer pots. The bonus with this variety- giant, white, fragrant blooms! Moonflowers are just as vigorous a vine, quickly growing 10'-12', covering trellises, arbors, etc. The most interesting thing about this plant is that the blooms open in the evening and last until morning, so be sure to plant this one where you will be able to see it at the appropriate times!
