It's ironic because I'm presently working on a garden themed line of graphics. Never having gotten so much as a fingernail dirty planting anything, one would think I'd have no frame of reference for such designs.
Yet I know many gardeners - including my mother, who by temperament is most certainly a gardener, through sadly never had a garden to work in. But her many pots of plants in the house over the years testified to her love of the soil.
And really, who can stand, as we all do, at the threshold of spring and not anticipate the smell of freshly turned soil -- even if you ain't the one turning it!
