In flower beds

 

Flowerbeds in public green spaces are usually intended for consecutive seasonal plantings: flower bulbs in the spring, followed by annual summer flowers sometimes even followed by winter-flowering pansies. The objective here is to provide colour.

- In the best possible situation, spring-flowering bulbs are planted here in layers; the top layer can consist of early-blooming bulbs such as crocuses with another layer made up of a later-blooming variety planted beneath them. When the upper layer of bulbs is in full bloom, the second layer is steadily growing up between them. Just when the earlier-flowering variety starts to fade, the second layer with its fuller habit conceals them from view. Ideally, each of the layers is composed of a number of varieties that flower either more or less simultaneously or succeed one another in flowering. Such a composition will then provide at least six weeks of colour.

- Adding summer-flowering bulbs to planting beds used for flowering annuals is easy since both have to be planted during the same period. Begonias, cannas and dahlias as well as Ornithogalum, Mirabilis and Tigridia are rewarding summer-flowering bulbs that can turn a bed of annuals into something distinctive.
