One way to escape the winter blahs is to visit one of the indoor tropical oases around Boston. Here is our guide to greenhouses in the region:

Lyman Estate Greenhouses in Waltham

Dating to 1804, the Lyman Estate Greenhouses are said to be among the oldest surviving greenhouses in the United States. Plants include the estate’s signature camellias as well as orchids, grapes and (sprouting during a visit this January) pineapples.
