Description
Rock Isotome is a charming native perennial renowned for its abundant star-shaped flowers and excellent mounding groundcover habit that creates beautiful displays in Australian gardens. This hardy species produces masses of small star-shaped flowers that bloom from spring through autumn, attracting native bees and butterflies while providing continuous garden color. The fine, green toothed or lobed foliage creates attractive groundcover that forms neat clumps and spreading mats. Hardy and adaptable once established, it thrives in well-drained rocky or sandy soils and full sun to partial shade positions with good drought tolerance. Perfect for groundcover, rockeries, and areas where native perennials with reliable flowering create charming landscape displays with extended blooming periods.
