Each garden on the tour reflects this year's theme, "Enter the Garden." The showcased gardens range from places of tranquility and retreat to the worldly, exotic and sophisticated, to the whimsical and playful. As part of the event, the Carriage House at Gamble Garden will offer gently used garden furniture, antiques, home decor, china and linens for sale. Vendors also will be selling home-and-garden merchandise. There will be a plant sale with hard-to-find species and edibles, as well as container gardens designed by garden staff and volunteers. Location: 431 Waverly Street, Palo Alto.  For more info:  https://www.gamblegarden.org/category/spring-tour/
