A glad for people who would normally never grow them, 'Atom' is about half the size of regular varieties, growing to at most 3 feet tall. This 1946 classic blends easily into perennial borders, and it won't get lost because its flowers are blazing red cooled by a thin, silvery edge.

This 3-foot-tall, small-flowered perennial glad was originally collected from an abandoned home site in North Carolina. Pure yellow with a wildflowery grace, it seems to be a form of a wild South African glad introduced about 1900 as Gladiolus primulinus.

This 3- to 4-foot-tall glad has luminous deep purplish-rose flowers. It dates from 1959 and is called 'Fidelio' after Beethoven's joyous opera.

This perennial forms a shrubby upright clump 2 feet tall by 1 foot wide, with white mealy stems and glossy green leaves. It bears deep, lavender-blue flowers on tall spikes from early summer to frost. Salvias are some of the showiest plants for containers, annual borders, and mixed borders. Butterflies and hummingbirds love them.
