Our Favorite Purple Annual Flowers

Purple geranium is a hardy plant that boasts a smattering of gorgeous magenta-purple flowers early in the season. Blooming often continues throughout the summer in cooler areas.

Also known as a pansiola, Anytime® Viola 'Sugarplum' is a charmer. The trailing plants keep blooming in warm weather, after most violas stop, and add winter color to hardiness zones 5 to 10. Let them spill over the sides of containers, or mass them in the landscape for deep burgundy-purple color with hints of white, gold and lavender. For a long-lasting display, spend a few minutes every day or two dead-heading fading flowers.

Centaurea cyanus, cornflower or "Bachelor Button," is a small annual flowering plant. It is a lovely ornamental plant in its natural habitat of meadows and grasslands, flowering from June until August.

Common morning glory is a fast-climbing annual with trumpet-shaped flowers that may be blue-purple, magenta, pink or white. Needs full sun. H 18 ft (5.5 m); S 10 ft (3 m).

Give your garden a dose of stunning variety with tricolor morning glory, a purple bloom that boasts a sunburst of dazzling yellow and white at its center.

A member of the geranium family, these pretty pink and fuchsia blooms require little water.

Asters always provide brilliant color, but for a show year after year, grow perennial species. The New York Michaelmas daisy has the brightest colors, while Aster amellus is compact and floriferous. Both grow well in pots.
