The Eastside’s own Lake Washington Symphony Orchestra will hold a garden tour on June 26 as part of the organization’s largest fundraiser of the year.

The tour, which features three private gardens and a light reception at the Bellevue Botanical Garden, is the third annual fundraiser to support the LWSO. The orchestra re-formed in 2013 following a five-year hiatus.

At each of the private gardens, which remain secret unless one buys a ticket, select members of the orchestra will perform in small chamber groups.

“We’ve got some fabulous gardens,” said Martha Garrett, the tour’s coordinator. “The gardens we have are a little slice of heaven.”

Garrett spoke highly of the garden in Issaquah — huge, English and very special — but declined to give away too many details.

The gardens, by designer Dan Borroff and landscape architect Darwin Webb, are open 11 a.m. to 1 p.m. on June 26. The reception, which includes light refreshments, wine and more chamber music, runs from 1 p.m. to 3 p.m.

Tickets are $25 and can be bought online through Brown Paper Tickets, over the phone or by mail.

The orchestra has several other events on the horizon: a fall fundraiser on Sept. 10 at the Bravern in Bellevue, and the fall concert on Nov. 5 at Westminster Chapel.
