To obtain a uniform, even effect and a mass of color, plant a single species or cultivar in each container then group the containers together. Containers that are planted with bulbs that are having fragrant flowers should be placed near the house entrance where they may be fully appreciated. Pots that are used for spring bulbs may be used for summer-flowering plants later. When bulbs from these pots die down, lift and replant them in the garden or store them in a dry place and replace them with annuals or tender perennials.
Some larger bulbs are so striking that they can be planted on their own in containers. Alternatively, you can group several bulbs of varying heights and colors in a large container, like a half-barrel, to provide an attractive feature on a patio.
Windowboxes are another type of containers that can be used to plant bulbs. When planting in windowboxes make sure you choose smaller bulbs that are in proportion to the size of the container. Bulbs are excellent for planting in layers below other plants so you will make best use of a limited space. The bulbs thrust through the surface planting to create a pleasing contrast of height and form. To obtain a prolonged display of shapes and colors you can blend the plants with winter-flowering pansies and ivy, followed by trailing tender perennials and annuals.
