They said white flowers in the garden bring a sense of serenity, that color white symbolizes purity, innocence, love, elegance etc. I suppose white flowers can brighten up shady areas and bring quietness to the garden. In the evening, especially in the season of 'White nights' they can also make my garden come alive.

White flowers look interesting planted with green foliage plants, as Hostas, Miscantus, Conifers, Rodgersia, Potentilla. I usually plant white flowers mixing them with other colorful plants because white color always combines well with any plants in any garden.

When I'd been visiting the Wisley gardens in the UK I saw an all-white garden. I learned that to do it is more difficult than it looks. As you see on my photos color 'white' can often be partially yellow or creamy. Nevertheless, white flowers can be a spectacle in a garden, bringing a sense of coolness on hot days.
