Palm Dome

At 67 feet high with over 3,000 panes of glass, this iconic greenhouse is the largest in the Botanical Gardens.

Containing palms, evergreens, and other plants that benefit from warm, humid conditions, the Palm Dome is home to one of our most photographed and easily appreciated collections.

Palm Dome

The palm collection includes many different species from around the world.

Did you know that palms aren’t actually trees?

  1. Palms are really tall herbaceous plants!
  2. Palms grow in tropical and subtropical environments around the world.
  3. Some palms have tall, solitary trunks, while others have multiple trunks.
