Are you in the market for a 15-acre, world-class private botanical garden and estate with three residences, greenhouse facilities and more? You could do worse than Heronswood Gardens, which is located on the Kitsap Peninsula near Kingston, Wash. The former Mecca for Northwest gardeners, created by plant explorer Dan Hinkley and his parter Robert Jones, closed in 2006 after Hinkley and Jones sold it to the Burpee Seed Co. some six years earlier. The estate, previously offered for $1.8 million, will be auctioned on June 15. A minimum bid of $749,000 gets you in the game. There’s more information here.

NOTE: If you merely want to see the estate, not buy it, it will be open June 30, July 28 and Sept. 29 through The Garden Conservancy’s Open Days program.
