The garden bug's really hit my dad.
I promised him some seeds from what came up this year: echinacea, marigolds, cosmos from my garden. Snapdragons and Sweet William from Raphaella's. Black-Eyed Susans from the guys down the street.
Have also recommended snowdrop, crocus and tulip bulbs. He seems pretty bullish on daffodils, as well. (I like how they look, but am *really* allergic to them.)
