Bachelor Button – Blue Double

Price range: $2.50 through $18.81

Bachelor Button ‘Blue Double’ is a tall, resilient annual flower featuring brilliant, double-petaled blue blooms. A classic cottage garden favorite, this variety is especially striking in mass plantings and makes a standout cut flower for fresh arrangements.

Bachelor Buttons prefer full sun and well-drained soil and are among the easiest flowers to grow from seed, making them ideal for gardeners of all skill levels. While they can be started indoors, they generally perform best when direct-sown outdoors, where they establish quickly and bloom reliably.

In USDA Zones 7–10, Bachelor Buttons can be fall planted to take advantage of cool-season growth and early spring blooms. In cooler zones, sow in early spring as soon as the soil can be worked.

Their tall, upright growth habit and continuous blooming make them excellent for borders, wildflower meadows, or naturalized areas. ‘Blue Double’ is also attractive to pollinators such as bees and butterflies, contributing to a healthy, biodiverse garden.

SPECIAL NOTE: Bachelor Buttons (Centaurea cyanus) are considered invasive or regulated in certain U.S. regions. They are prohibited in North Carolina, monitored in Washington State, and listed as invasive in West Virginia, Georgia, and parts of eastern Oregon. If you live in one of these areas or are concerned about their spread, you can still enjoy them responsibly. Regularly cutting the flowers for bouquets and deadheading spent blooms will help prevent self-seeding. Monitor their growth closely to keep them from spreading beyond your intended planting area. As always, check with your state’s Department of Agriculture or consult the USDA’s invasive species list before planting.
