Family: Malvaceae
Alyogyne huegelii, commonly known as lilac hibiscus, is a fast-growing shrub native to Western Australia. It is prized for its showy, hibiscus-like flowers that range in color from pale lilac to deep purple, with blooms that can appear nearly year-round in warm climates. The plant has deeply lobed green leaves and a rounded, shrubby growth habit, making it a popular choice for ornamental landscaping in dry or coastal areas. Although it resembles true hibiscus species, lilac hibiscus belongs to the mallow family and is well adapted to hot, sunny conditions and well-drained soils.
In Hawaiʻi, Alyogyne huegelii is only found in cultivation and is valued primarily as a decorative garden shrub. Its drought tolerance makes it a good option for low-water landscapes, and it provides long-lasting color in gardens and yards. While not known to be invasive in the islands, gardeners are encouraged to manage it responsibly and avoid planting near natural areas where it could potentially spread. This attractive shrub is best suited for cultivated landscapes where its striking flowers can be appreciated without risk to native ecosystems.
