This classic cutting-garden annual comes in shapes and sizes that most people have never even tried. Growing from seed will allow you to experiment with more than the usual suspects you see in garden centers: there are the brainy-looking “crested” celosia shown above (C. argentea cristata), soft plumed varieties (C. argentea plumosa), and fluffy arrow-shaped types (C. argentea spicata). All are superb for adding texture in the border or the vase.
Sunflowers are colorful giants and are one of the first flowers many children will recognize. A sunflower-growing competition appeals to any age of gardener.
