Very few early-flowering bulbous, tuberous and cormous plants are as extensively planted as the Crocus. Indispensable for each and every garden, they join snowdrops, winter aconites and glory-of-the-snow as the very first heralds of spring. More than 100 species are known, but only thirty have been cultivated. Most common crocus varieties have little or no scent, but a few of the choicer ones are quite fragrant. Although you may not be spending much time outdoors in early spring, that is no reason not to plant fragrant spring bulbs around your walkway, deck or patio.
Here is a list of fragrant crocus, which will also fill your garden with their wonderful color and charm! Masses of them often produce a spectacular effect.
