Bachelor’s Buttons

This flower’s ruffled blue blooms create carefree drifts of color perfect for planting beds. This cottage garden favorite also comes in pink and white and is ideal for bouquets. Blooms beckon butterflies; seedheads lure birds.

Plants self-sow freely. Remove spent flowers to limit self-sowing. Look for seedlings or sow seed in fall in warm zones; in cold regions, sow seed outdoors in spring 7-14 days before the last frost date.

Plant size: 12-36 inches tall, 12-18 inches wide

Where to use: Well-drained soil in full sun to light shade; plants tend to droop in too much shade

Calendula

The daisy-like Calendula flowers unfurl in a variety of colors, including traditional yellow, deep orange, pastel hues and bicolor blends. Flowers may be single or double and can self-sow.

Pinch seedlings to encourage branching and more blooms. Removing spent blossoms promotes more flowers to form. Petals and leaves are edible. Add fresh or dried to salads, soups, or rice, or use blooms to garnish desserts.
