Many silver-leaved plants are naturally drought tolerant and are used in xeriscapes, or dry gardens.
These guidelines are all dependent on Mother Nature, of course, and your location. For the Boston area, Zone 6 hardiness puts the last frost date around May 1. For Zone 5, add a week; Zone 4, add two. But that doesn't mean cold nights are gone for good. Keep a careful eye on your local weather forecast to watch for unseasonably cold temperatures. Find your USDA Hardiness Zone at www.garden.org/zipzone.
