National Public Gardens Day is presented annually by the non-profit American Public Gardens Association (APGA) in partnership with Rain Bird. Both are committed to celebrating the environmental stewardship of North America’s public gardens and their local, regional and national leadership in resourcing the nation’s conservation and environmental education needs.

National Public Gardens Day, which this year fall son Friday, May 6, celebrates public gardens of all varieties and each institution participates in their own unique way.

Highline SeaTac Botanical Garden in North SeaTac will, as always, be open to the public (and free of charge) from dusk to dawn.

Another wonderful local garden participating in National Public Gardens Day is PowellsWood: A Northwest Garden, nestled on the upper edge of Redondo along Dash Point Road.

In support of National Public Gardens Day, Better Homes and Gardens is offering magazine readers a free admission coupon for two to visit a public garden on National Public Gardens Day, May 6, 2011—including PowellsWood, which normally charges $5.00 per person.

The coupons will be valid at all participating public gardens on that day only. Readers can obtain the coupon on the Better Homes and Gardens website.

The preliminary schedule of events at PowellsWood includes a presentation on flower photography by the SeaTac Blog’s own Jennifer Leone at 12:30 plus other photographic art from Tyee Photography Alliance.
