Isotoma axillaris is a delightful Australian native perennial renowned for its masses of beautiful, star-shaped lavender-blue flowers. This charming plant produces a spectacular display of delicate five-petalled blooms that contrast beautifully with its finely divided, bright green foliage.
Flowering generously throughout spring and summer, Rock Isotome adds a lovely splash of colour to garden beds, rockeries, borders and containers. Its naturally soft, spreading habit makes it particularly attractive when planted along pathways, between rocks or where its flowers can spill gently over garden edges.
Hardy and easy to grow, Isotoma axillaris thrives in a sunny to partly shaded position with well-drained soil. Once established, it tolerates short dry periods, although occasional watering during hot weather will help maintain vigorous growth and flowering.
Its beautiful flowers also attract bees and other beneficial pollinating insects, making it a wonderful addition to wildlife-friendly gardens.

At Aussie Plants Online, we love Isotoma axillaris for its gorgeous lavender-blue, star-shaped flowers that seem to float above its delicate green foliage.
We particularly love the way this little Australian native brings a soft, cottage-garden feel to native plantings. Its long flowering period, cheerful colour and ability to fill small garden spaces make it a wonderful choice for adding colour without overwhelming surrounding plants.
It looks especially beautiful planted alongside low-growing grevilleas, native daisies and other colourful Australian wildflowers.
A delightful Australian native that rewards gardeners with masses of beautiful blue flowers and a lovely, relaxed garden appearance.
