The seed displays got me thinking about annuals. In my perennial gardens, I always leave large empty spaces to grow my very favorite annual - Zinnia Swirls. Back in the late 90's, I bought one tiny packet of 'Assorted Zinnia Swirls' at a Madison garden center. I've been saving the seeds ever since. I keep the dried seeds over the winter, then in spring I sow them directly in the garden (no starter pots) around Memorial Day. No special care needed. They bloom reliably from July until frost. The assortment of colors is amazing -- whites, reds, purples, pinks, electric oranges and magentas with single, bi- and tri-color blooms. I don't make much of an effort to separate the seeds by color so I usually have clumps of several colors. And no two flowers look exactly alike. Love, love love my Zinnia Swirls!
