Ladew, Longwood, Brookside, Winterthur -- standout gardens familiar to many Marylanders. But those shouldn't be the only botanical destinations on your map. There are other gardens -- less well-known but just as impressive -- all within a two-hour drive of Baltimore. No better time than now to explore them. What's so significant about these almost-secret gardens? Diversity. No two are alike. There's an outdoor sculpture garden and a natural habitat with indigenous plants. Wildflower gardens and woodland trails, along with formal gardens accompanied by historic houses -- even one with an archaeological dig. We have geography and climate to thank for much of this diversity.
