Summary

The garden features 16 acres of lush woodlands and garden spaces, with over 2,000 species of plants and trees. It is a great destination for nature lovers, botanists, and families looking for a peaceful retreat from the city.

One of the main draws of Leach Botanical Garden is its stunning collection of rhododendrons, which bloom in the spring and early summer. Visitors can also explore the various trails and gardens throughout the property, such as the Fern Dell, the Upper Garden, and the East Terrace.

Another highlight of the garden is the Leach House, a historic home that serves as a museum and event space. The house was built in the 1930s by botanists John and Lilla Leach, who founded the garden as a living laboratory for their research on Pacific Northwest plant life.

Visitors can also participate in various events and programs hosted by the garden, such as guided tours, workshops, and seasonal celebrations.

Overall, the best time to visit Leach Botanical Garden is in the spring and early summer, when the rhododendrons are in full bloom. However, the garden is open year-round and offers something for visitors in every season.
