On Thursday, July 16 at 7:30 pm join Tim Wood, the Proven Winners Plant Hunter from Spring Meadows Nursery, as he takes you around the world to look at eight beautiful and diverse species of hydrangea. Find out which are best for your garden, how to grow them and meet the breeders that developed the best new selections. Tim will take the mystery out of growing hydrangeas; you’ll learn how to get the best blooms, how to prune and how to change the flower color. The program will be held at the Polly Hill Arboretum, 809 State Road in West Tisbury. $10/$5 for PHA members. For more information visit www.pollyhillarboretum.org or call 508-693-9426.
