Description
If you’re looking for a tough-as-nails plant that brings a touch of wild elegance to your garden, meet the Native Iris, or Western Patersonia. This Aussie native is a real gem, thriving in conditions that might make other plants throw in the towel. Growing from a sturdy underground rhizome, it’s built to handle the Australian climate, making it a dream for gardeners who want beauty without the fuss.
From spring through summer, this little wonder puts on a show. Its strappy, grass-like foliage forms a lush green base, while long stems rise up, topped with stunning purple flowers that seem to dance in the breeze. The flowers only last a day but a well grown plant will produce good numbers over the season, making them worthwhile for landscaping and garden use.
The Native Iris is a sun-loving, drought-tolerant champ, perfectly suited to dry, warm climates and sandy soils. It’s right at home in cottage gardens or coastal settings, and it’s even tough enough to handle light frosts. Plus, it’s a magnet for beneficial insects, doing good work for your garden ecosystem.
A little tip for seed starting: a bit of smoke treatment to kickstart germination. It’s like giving them a little wake-up call to get growing!

Mulching
- Apply a light layer of mulch (e.g., gravel or coarse sand) around the base of the plant to retain moisture and suppress weeds.
- Avoid heavy organic mulches, as they can retain too much moisture and cause fungal issues.
