One very pleasant aspect of a window garden is that it can be redesigned on a whim. I tend to change mine with the seasons, or whenever I want the window to feature a particular theme.
For Thanksgiving one year, I composed the garden in my upstairs bathroom almost exclusively with plants from East Africa. These included standard, miniature and trailing Saintpaulias, which adorned the sill and shelves. Tolmiea menziesii (left), the fascinating “piggyback plant,” and a pink double impatiens (right), survey the world from brackets.
