Croquet much? With a history that goes back centuries, the anachronistic sport of genteel backyard gardens doesn’t seem relevant in the 21st century, but consider this: Anyone who can stick a wicket in the ground and knock a ball around can play, making croquet the grand old aunt of such family pastimes as miniature golf — and it’s pretty hard to injure yourself doing it. With that in mind, Denver Botanic Gardens is cueing up a summer of sport with a Croquet in Bloom series, pitting adult teams of two against one another in monthly summer tournaments for a chance at grabbing the first annual Denver Botanic Cup in September. It all starts Saturday, June 10, at 4 p.m. at the DBG, 1007 York Street, and continues at the same time on July 8, August 12 and September 23. Tickets are $15 for participants and $5 for spectators; buy them and sign up at botanicgardens.org.
