I also have a small white garden. It is one of my favorite little nooks. It looks wonderful in the moonlight. Planted in it are bleeding heart, liatris, early mini daffodils, crocus, hyacinths-both giant dutch and grape, astilbe, ghost fern, Jack Frost, edelweiss, dianthus and a mini rose. It also contains self seeding allysum and pansies. Each year I fill it in with whatever white flowering annuals look good at the moment, usually ending up with snaps, cleome, dusty miller, salvia, cosmos, petunias and verbena. I can see the garden at night from my covered porch. It brings me much peace and pleasure.
