White garden like Vita Sackville West at Sissinghurst
I'd like to create a tiny version of a White Garden using Vita Sackville West's inspiration. I have a site that is 5 feet by 10 feet and gets about 5 or 6 hours of direct sun a day. The site will be seen from our patio and/or sunroom and is backed by a white barked birch tree. The tree is at the top of a ravine at least 10 feet behind the site. I would like suggestions of plants that might be attractive for as much of the season as possible and would compliment eachother. Flowers, or foilage should be white or gray. Please tell me what are your thoughts? Thank you in advance for anything you might suggest.
