| Hi melanie, Here is a list of what I have. Some are not complete names because they were given to me by friends. Don't forget to use foliage that is variegated as well. My garden is a combination moon garden and fragrant garden. Still all the flowers are white. There are shady places and sunny places in the garden so I plant accordingly. Don't forget to use white garden ornaments to give it "POW". I have a hat birdhouse with a white dress and pearls hanging on a tree. The ice storm a couple of months ago brought down the tree unfortunately. I am thinking of planting a white fringe tree or orchid tree in the spot. Hope this helps you.
