Foliage plants are the unsung heroes of the garden. Grown for their striking leaves rather than their blooms, foliage plants add texture and movement to landscapes. They can be used as filler between flowers or as a focal point. While the flowers of foliage plants are often underwhelming, these species boast beautiful leaves in an array of colors, shapes, textures, and sizes. To help you realize the full potential of foliage plants, we spoke to gardening experts who shared a few of their favorite varieties.
