Lava Dubautia: A Hardy Hawaiian Native for Your Dry Garden
If you’re looking for a resilient native Hawaiian plant that thrives in tough conditions, meet the lava dubautia (Dubautia ciliolata ciliolata). This unassuming little shrub has earned its common name by literally growing on lava flows, making it one of nature’s ultimate survivors. But don’t let its tough-as-nails reputation fool you – this plant brings subtle beauty and ecological value to the right garden setting.
What Makes Lava Dubautia Special
Lava dubautia is a perennial shrub that typically grows as a multi-stemmed woody plant, usually staying under 13-16 feet tall. Its narrow, silvery-green leaves create an attractive backdrop for clusters of small yellow composite flowers that appear throughout much of the year. The plant’s compact, branching form gives it a naturally sculptural quality that works beautifully in modern landscape designs.
Where It Calls Home
This hardy native is found exclusively in Hawaii, where it has adapted to some of the most challenging growing conditions imaginable – including fresh lava flows and rocky volcanic terrain. Its ability to colonize these harsh environments makes it an important pioneer species in Hawaiian ecosystems.
Important Conservation Note
Lava dubautia has a Global Conservation Status of S3T3, indicating it faces some conservation concerns in its native range. If you’re interested in growing this plant, it’s crucial to source it only from reputable native plant nurseries that propagate their stock responsibly rather than collecting from wild populations.
