Standing Tall: A Texas Tree Festival is an annual family-friendly celebration of trees at Houston Botanic Garden in Houston. Wander the garden's green spaces and join in tree-themed crafts and activities, guided walks, food and other vendors, and live entertainment. It's a leafy, laid-back way to spend a Sunday morning outdoors. Bring the kids, bring your curiosity and bring a friend who loves plants. You'll leave with a new appreciation for the trees that shape Texas.
