Bachelor's buttons bear charming and prolific flowers in hues of blue, pink, lavender, white, and maroon. Those with a true blue color are especially welcome in the garden as that color is rare in nature. Each disc-shaped flower is about 1.5 inches across, with ragged petals radiating out from the center.

This upright, 30-inch-tall, bushy annual cloaks itself all summer in purple blossoms up to 2 inches across. But more important, it is the forebear of scores of varieties that can be found in almost any place you can buy seeds. There's the Whirligig Series, the California Giants, the Profusion Series, the State Fair Series—the list goes on and on.

This annual series is comprised of dwarf, compact plants, 10 to 12 inches tall and half as wide. They bloom all summer with fully double blossoms, to 4 inches wide, in apricot, ivory, red, yellow, pink, and many shades in between.

Feathery, almost fern-like leaves are mid- to dark green. In summer, larkspur bears delphinium-like open to densely packed spikes to 24 inches tall of pink, white, or violet-blue double flowers.
