It is a little known fact that it is possible to have garden bulbs flowering all through the year.
The Bulb Flowering Calendar below is for Start of the Main Flowering Times. Summer flowering bulbs in particular, will flower over a longer period than the spring and autumn flowering bulbs. There will be different flowering times according to which part of the world you live. The periods outlined are for general UK areas.
Some 'bulbs' that we list for all year round colour are not true buls, but often known as such - such as the hardy Cyclamen - which of course is a corm.
Tubers; Corms: Rhizomes: Stolons and all other types of underground storage organs are listed. Most you will find in the 'bulbs' sections of catalogues and garden centres.
