Public greenhouses in the Washington area
Public greenhouses -- some small jewels, others crystal palaces -- can introduce you to the delights of plants under glass that at best will inspire and at least offer you the pleasures of a greenhouse without the fuss. Here are a few favored by The Post's Adrian Higgins.
The zoo's Amazonia house features a two-story re-creation of an Amazon rain forest under glass, including exotic fish and birds. Open daily 10 a.m.-4:30 p.m.
3001 Connecticut Ave., NW.
U.S. Botanic Garden
As Washington's most lavish plant conservatories, the botanic garden features a central "jungle," with an elevated walk in the canopy, surrounded by a series of smaller greenhouses and halls representing plant habitats. Open daily 10 a.m.-5 p.m. 100 Maryland Ave., SW. 202-225-8333. http:/
