The first bulbs in flower are usually snowdrops but these are best bought as plants in flower or still with their leaves on as the bulbs don't store well dry. You can also beg some from friends or neighbours next spring as trhey benefit form being regularly lifted and split.
Crocuses are generally next but need full sun for the flowers to open. Usually, white, yellow, purple or striped. Lots of sizes available.
Daffodils/narcissus come in a wide range of heights and sizes as well as colours now. They'l be in teh shops from the end of August and can be planted as soon as you've bought them as they'll start putting out roots straight away. In the taller ones I like Thalia and Ice Follies and in the wee ones I like Minnow. If your garden is sheltered from strong winds, Pheasant's Eye narcissus has delicate flowers and good perfume.
Hyacinths come in a wide range of colours now and are usually scented.
Tulips like full sun and good drainage and are usually treated as annuals but if you plant them deep and choose your varieties wisely they'll come back. I don't grow many except for some species as my garden is too fertile and moist.
There are lots of other bulbs to fill the gaps - scillas, chinodoxias, dwarf iris, fritillaries, alliums for later on.
Have a google round the RHS website for info on cultivation and websites such as this - http://www.greengardenflowerbulbs.nl/en/ just to get a feel of what there is and then go to yourlocal garden cnetre or big DIY store from late August on to see which ones they offer. Too easy to go mad in a catalogue!
