When we think of combining flowers in a flowerbed or border, the first consideration that usually comes to mind is color. Do we choose warm oranges and yellows, or cool lavenders and whites? Or do we combine the two, juxtaposing orange and yellow with deep violet, for example? Of course, color isn’t the only issue. Plants have other features that we should also take note of, such as height, foliage, and, in particular, bloom time. (There’s no point in combining flowers if they bloom at separate times of the growing season.) Then, we need to ask if they have the same cultural needs—shade vs. sun, or damp vs. xeric, for instance.
But how often do we consider flower shape when pairing blooms?
