Small Colorful Trees for Year-Round Interest in a 3×3-Foot Bed

For a 3×3-foot bed next to a green hedge: a tree will outgrow it fast. Choose compact shrubs with colored foliage: Weigela (burgundy/gold cultivars), Barberry (red/purple/orange), or dwarf Japanese maple (if zone allows). Use growit.com/PlantInfo/LandScape.Htm with your USDA zone to filter by color, size, climate.

Zone 7 example: 'Wine & Roses' Weigela, 'Crimson Pygmy' barberry. Small space = shrub, not tree.
