About Botanic Garden Atlas

Botanic Garden Atlas is a directory and map of botanical gardens and arboretums in the United States. For every garden with its own page it shows the position on a map, the official website where one is known, the nearest other gardens, and sunrise, sunset and hours of daylight for 16 dates in 2027.

What we show

760 botanical gardens and arboretums are listed. Each garden page shows where the garden is, a link to its official website when we know one, nearby gardens with straight-line distances, and a table of sun times for the solstices and equinoxes plus the daylight on the 15th of every month. State, county and city pages show how many gardens are listed and the range of daylight across them.

Sun times are not opening hours

Calculated for the garden's map position and a flat, open horizon. Trees, hills and buildings change what you see on site. These are sun times, not opening hours.

Before you go: hours, tickets and access are not listed here. Check the garden's own website.

What we do not show

• Opening hours, tickets, prices, membership or events.
• Whether a garden is open to the public, accessible, or has parking.
• Bloom times, plant collections, acreage, founding years or descriptions.
• Ratings, reviews or rankings.
• Driving routes or travel times: distances are straight-line.

Pages appear in stages

The directory is published in batches. A garden gets its own page and map pin when its batch is released, and a state, county or city gets a page once at least three of its gardens have one.

Where the data comes from

The sources are listed in one place, the privacy policy.
