Celebrate Arbor Day at the Houston Arboretum and Nature Center, a lush 155-acre nature preserve and one of the city’s greatest natural treasures. Learn all about native trees and partake in tree planting demos and tree tours.  Kids’ activities will include papermaking, face painting, puzzle hikes, recycled paper hats, leaf rubbings and more. Tree seedlings will be available for a small donation and larger native trees and shrubs will be available for sale.
