Tulips grow from bulbs not catalogues but I guess that is obvious. Nevertheless I think the first job is to check over any Tulip bulbs you lifted last spring to dry off. Bin any with mould or soft centers, do not add them to your compost heap.

There are many bulb catalogues now available and they usually supply a lot of information about the Tulips origin, size and flowering characteristics. If you are not on a mailing list you can respond to numerous off the page adverts in the press and magazines.
I like J Parker for the range and wholesale prices on larger volumes.
Bloms bulbs have been around for over 100 years and supply good size bulbs at a price and DeJager is another old established supplier.
Spalding bulbs are over marketed with too many gimmicks and free gifts so personally I tend to avoid them.
Of the many other bulb sources most seed companies supply bulbs by mail order but I particularly like the niche suppliers like Miniature Bulbs.

The big plus from mail order catalogues is that you can browse the pictures and specifications selecting the types and varieties you want. On the down side you are trusting that a good sized bulb will be supplied (a good big one beats a good small one). Remember too complain if you are unhappy with the bulbs you get, most companies value their reputation amongst gardeners.
