There's even a section for poisonous plants. The winter garden includes evergreens, conifers, and assorted plants with interesting cold-weather colors and textures. The complex's arboretum includes an area with sculptures. Walking and bus tours are available; call ahead for seasonal times. Some tours are free and others are $5.
