There are actually many different species of crocuses. However, in most gardening catalogues you will normally see only two categories of crocuses mentioned: the Giant Dutch Crocuses, and everything else (sometimes the term Snow Crocuses is used). I'm going to do the same. First, the Giant Dutch Crocuses:

Giant Dutch Crocus

As the name suggests, this is the largest type of crocus, although "large" is certainly a relative term when you're talking about crocuses. Giant Dutch Crocuses are typically only about 4 - 6" (10 - 15 cm) tall. These crocuses are extremely popular and deservedly so. They come in gorgeous colours and look terrific when planted in large numbers ("drifts").

An odd number of crocuses (5 or 7) of the same colour planted in a rock garden is also very effective. They naturalize (i.e. come back year after year and slowly multiply) quite easily and require almost no care. Giant Dutch Crocuses are a must in anyone's spring garden.
