Cannas, begonias and dahlias are available in a wonderful array of colors and can be started into growth in late winter or early spring so that they produce a mass of flowers throughout summer.
Cannas and dahlias should be planted into, and begonias should be placed on top of, barely moist compost and kept in a light, cool to warm place until growth begins at the roots.
Increase the available moisture once leaves begin to emerge.
In mild spells, when the ground can be well dug, plant lilies in the border, either singly or in groups of three or more.
Alternatively, plant them in deep containers.
They thrive on well drained soil, so add a layer of grit beneath the bulbs in both borders and containers.
This is a time when attention to watering is crucial, especially with container grown plants.
Moisture is necessary to bulbs at all stages of growth, and it is important to check that the compost soil mix is moist in all pots, troughs, window boxes and hanging baskets from autumn right through to spring.
Pots and troughs will probably fare best, but window boxes and hanging baskets tend to dry out quickly.
Lack of moisture in late autumn and early winter will inhibit root growth, and lack of water in late winter, when the leaves and buds are emerging, is also detrimental.
Keep an eye on the compost and water as necessary.
Do not, however, be tempted to water if frost threatens, as bulbs will not appreciate having their roots in wet, frozen conditions.
It is much better to ignore any bright sunny days when nights are likely to be frosty, and water only on overcast days when the nights will be milder.
