Spooky Season-al Color at the Arboretum with Cynthia Welte
Members: $35. Non-members: $45.
October 21, 2025 @ 10:00 AM - 12:00 PM
“Spooky Season” encompasses all that we love as the chill of autumn approaches: the imagery and customs associated with Halloween and fall, like ghost stories, cozy sweaters, crackling leaves underfoot and gathering mist. In this tour of the Washington Park Arboretum, UWBG Tour Guide and NHS Board Member Cynthia Welte will highlight striking autumnal color interwoven with stories about creepy and sinister plants in the Arboretum collection. (Poisons, witches, fairies and a botanical touch of the dreadful!) You’ll be guided through the vibrant Japanese Maple collection, Sorbus collection and more. Learn the folklore behind some well-known plants, meet new favorites, and be amazed at the mysteries of leaves and fall color. Be not afraid – this tour takes place during daylight hours.
