The early arrival of hot weather around here cut into the flower-blooming season. It also hastened the formation of seed pods seen dangling from an ancient wisteria vine clinging to the garage. Wisteria, a member of the pea family, reseeds through a process called “explosive dispersal,” according to a blog by the master gardeners of Santa Clara County, Calif. In other words, the pods continue to heat up and dry inside and boom! They “explode.” One gardener wrote that it’s quite a sight to see. So when you walk by our wisteria, stop and take a look at the pods: You may see nature at work. But be careful!
