Belmont commercial landscaping firm Waverly Landscape Assoc. Inc. has been acquired by California’s ValleyCrest Landscape Co., a merger ValleyCrest says has created the largest landscape company in the Northeast.

The combined landscape operation, with sales of $45 million, will serve more than 300 commercial customers in Greater Boston, according to a statement.

Since 2001, ValleyCrest has operated a landscape construction and maintenance location in Boston. The company has built numerous landscape projects at some of the area’s most recognizable locales, including the Big Dig, Massachusetts General Hospital, Boston Children’s Museum, MIT, Eaton Vance’s Roof Garden, Blue Cross Blue Shield of Massachusetts and Patriot Place.

"This is a terrific opportunity for ValleyCrest to partner with the largest market leader who shares our vision for great landscapes, has a passion for outstanding customer service and seeks to drive value to customers through operational excellence," said Richard A. Sperber, president and CEO of ValleyCrest, who also noted that the addition compliments the company’s existing operations in Boston.

Two hundred members of the existing Waverly team and workforce, including founder Paul Tocci, will join ValleyCrest Landscape Maintenance as part of the deal. Financial terms were not disclosed.
