• Dodonaea viscosa ‘Purpurea’, commonly known as Purple Hopseed Bush, is a fast growing evergreen shrub that brings height, movement, and rich color into the landscape. It’s often used when you need quick screening without sacrificing style.
• The foliage is narrow and elongated, with a deep burgundy to purple tone that intensifies in full sun. The leaves move easily in the wind, giving the plant a light, dynamic feel despite its height.
• It naturally grows upright with a slightly open structure, making it ideal for hedging, screening, or creating vertical layers in a planting. It can be kept more formal with regular trimming or allowed to stay loose for a softer, more natural look.
• Because of its speed and adaptability, it’s commonly used to establish privacy quickly while still fitting into a designed landscape.
• Dodonaea ‘Purpurea’ grows best in full sun and prefers well drained soil. Once established, it is highly drought tolerant and performs well in warm, dry conditions.
• It typically reaches about 10 to 15 feet tall and 6 to 8 feet wide, though it can be maintained smaller with pruning. It is well suited for USDA zones 9 through 11. The foliage is evergreen.
• This plant has low toxicity and is generally safe for gardens with pets and children.
• The flowers are small and not especially noticeable, but female plants may produce decorative, papery seed pods.
• It is generally deer resistant.
• Dodonaea viscosa ‘Purpurea’ fits especially well into Mediterranean, modern, and screening-focused garden designs, where its color and height can be used to create contrast and privacy.
• It pairs well with plants like Westringia fruticosa ‘Smokey’ to create a cohesive, drought tolerant palette, Anigozanthos ‘Bush Gold’ to introduce bold vertical color, Grevillea species for textural contrast, and Agave desmettiana ‘Variegata’ to add a bright, structural focal point at the base.
• Expert Tip:
• Place this where you need fast coverage, because it fills in quickly and creates an effective screen in a short amount of time. Regular light pruning will help keep it dense and prevent it from becoming too open or leggy.
