Welcome to Open Days

Registration for Open Days will open approximately two months prior to each event.


We made several big changes to the program last year, all of which will remain in place for our 2023 Open Days season, including:

  • Online pre-registration is REQUIRED for each garden. In our calendar of Open Days, please click and register for each garden you would like to visit. Children under 12 are free and do not need to be pre-registered if accompanied by a pre-registered adult.
  • Capacities are limited. Sorry, no walk-ins allowed; no paper tickets or cash payments will be accepted on-site.
  • Masks are required, at the discretion of the garden owners, and social distancing is encouraged at all in-person events.
  • Registrations are non-refundable. Sorry, we are not able to offer reimbursement or exchanges unless we cancel the event.

Welcome to Open Days—Tours of America's best private gardens

Fueling America’s passion for gardens, Open Days is a nationwide community of gardeners and garden enthusiasts teaching and inspiring each other. From expert to novice, we think there is no better way to improve as a gardener than by experiencing a diverse range of gardens, and gardening traditions, firsthand. Open Days provides opportunities to visit the country’s most exciting, creative, and innovative private gardens. It has become our best-known and most beloved program.

Since 1995, Open Days has welcomed more than 1.4 million visitors into thousands of inspired private landscapes—from urban rooftops to organic farms, historic estates to innovative suburban lots—in 41 states. Open Days is made possible thanks to the hard work and generous support of hundreds of volunteers who help us showcase regional horticultural and stylistic expressions in a national context, celebrating the rich diversity of American gardens.

About Garden Extras, Digging Deeper, and the Garden Masters Series
Many Open Days hosts supplement the guest experience with guided tours and additional activities such as book-signings, plant sales, or demonstrations. These Garden Extras are free with Open Days garden admission.

Inspired by the rich informal conversations that typify Open Days, special site-specific programs were added to enhance the Open Days roster in 2015 and quickly became popular. In these Digging Deeper events, small groups of visitors come together for informative yet informal talks and demonstrations with experts from every facet of the garden world: landscape architects, garden writers, plant collectors, artists, and more. Digging Deeper programs are a fantastic opportunity to explore the myriad connections between gardening and other creative pastimes. Advance registration and pre-purchase is required. Space is limited and they fill up quickly!

In 2019, we introduced the Garden Masters Series: connoisseur-level educational and social opportunities at exclusive gardens not otherwise available through Open Days. These events provide a chance for deep learning, inspiration, and a unique experience with like-minded friends and fellow garden enthusiasts.
