So many annuals to love -- doesn't anyone else like the humble marigold?? Scratch up the ground, sprinkle some seed, add water.... ditto to cosmos, which also self-seeds even here in the north pretty reliably. But for the flower boxes that I hang off the deck railing, on the S side of the house, I still like petunias, and this year I think I discovered the secret to keeping them looking good throughout the season. Of course I've always attempted to keep them deadheaded, etc., but this year, though a combination of circumstances, I planted about twice as many plants in each box as normal, some were quite immature when first planted and the others were already flowering; then, on top of deadheading, I was able to trim down the plants as they started getting lanky, and it was never even noticeable that I had removed some flowers. At any rate, I'd hate to have to just pick one to grow, because impatiens for the shady areas are also a must in my garden!! And sunflowers... morning glories...
