When I think of a moon garden I think of scented plants first rather than just white and green. I like jasmine, pflox, and brugmansia. I think of a place to sit and enjoy the peacefulness of the night in the garden, so whatever is planted there can be enjoyed while relaxing in the cool air. I like the sound of running water too, not a torrent or a waterfall, just a soft splashing sound and the peeps of frogs and crickets nearby. This is the garden I have, and it's a half-moon shaped area inside the turnaround driveway in front of my house. The long straight side that faces the street of the half-moon is enclosed with a brick and iron fence. The half-circle side is marked out with stone that edges the driveway. There are two entrances to this garden, the main entrance has an arbor, the second entrance is just a little footpath. The paths allow you to see all of it, but also require some back-tracking so you get to see some areas from two directions. One circular path has a stone castle in the middle that is inhabited by fairies, or gnomes, I'm not sure which, since I've never seen them, but their tracks are all over the place. They leave their "stuff" laying around, ladders, chairs, dishes, stuff like that. They're kinda messy sometimes, but I let them stay anyway. Passers-by often pull over and peek through the iron fence since there is enough color and interest for it to be eye-catching during the daytime. Nobody stops at night though, because they can't see how wonderful it is in the dark.

I love the white annual vincas, either solid white or with a pink or red eye. They line a pathway nicely, some come back the following year if the winter is not too bad. And I like the chartreuse ornamental sweet potato as well. They are close to white, being so reflective, and they make purple tubers that can come back the following year as well. They would work well in bright sun, of course. And then I also love the white star jasmine as a sweet smelling vine that is ever green down here in AL. Lambs ear is another nice gray-leafed plant with small pink blossoms. And you can also get hold of some aztec grass which is like leriope and monkey grass, but is paler green/white striped like a spider plant. They also have a really fine variegated ajuga reptans which is pale green/white leafed, ground cover and has spikes of pink or blue fuzzy flowers. Getting a spot of variegated ginger is also a good idea, or maybe some of the hardy aspedistra, cast iron plants, which love shade, can take dryness, and come in striped green/white long leaves. I LOVE these tough customers, and have planted many of them at the back of my flower beds. For spring, look for the wild white violets and pull them out of the lawn and into your low borders. They don't last long, but they are fine for the time they bloom. And then don't forget the variegated hostas, I have learned to love them up north, and now am pleased that there are some varieties taking a little more heat as long as we give them shade. Oh yes, if you can get some of the green/white caladium bulbs, they will brighten up a row of small boxwood under a big shady oak tree, they don't like too much sun. And just like narcissus, the critters love to eat the bulbs. sigh... what we must go through to keep a variety in the gardens!

By now everyone's seen this so letting it drop down.

When you specify "tall, flowering" how tall are you aiming at? Toad lily/Tricyrtis hirta grows to 3 ft. tall and blooms here in southern New England (z6a) end of September/ beginning of October every year, is zero maintenance, doesn't spread, not bothered by predators and helps sustain pollinators.
