About Artichoke

Artichokes are dramatic architectural plants that produce large thistle-like flower buds for eating. A perennial in mild zones, they need a long warm season. The giant silvery plants become a striking garden focal point.

Start indoors 8-10 weeks before last frost. Vernalization (cold treatment of seedlings) improves first-year flowering — expose seedlings to 10 days below 50°F. Give each plant 4x4 feet of space. Cut main bud before it opens; side buds follow.
