As Lisa notes, the areas where I have seen fireflies have areas of long grasses.
The other consideration is: maybe you already have some. You just need to be ambling about an hour or two after dark, in the right area, when they are out looking for love. Most citizens will swear that there are no fireflies in their parks, and yet when I take a quiet midnight stroll they are bopping around. Magical!
