Boston Ivy can be planted in areas of full sunlight, partial shade or full shade. Talk about indecisive…

Parthenocissus tricuspidata or Boston ivy is a self-clinging climber with green summer foliage that becomes a vibrant purple or red in autumn. The leaves are generally oval-shaped or three-lobed. Boston ivy has small green flowers during summer and blue berries during autumn. This climber grows in any soil that is fertile with good drainage. Boston ivy can be planted in areas of full sunlight, partial shade and full shade, though for maximum impact from autumn colouring this plant should be placed in partial or full shade. Boston ivy should be pruned during autumn or the beginning of winter to keep it in check. This striking climber will definitely draw attention with its vivid autumn colouring and is a good choice for use with trellises and arches or on fences and walls.
