Kirsten Parris knelt on a Melbourne sidewalk, counting bees on a patch of purple flowering mint next to a busy road. Just weeks earlier, this nature strip was bare grass. Now, it buzzed with life. Along with 13 other residents in Brunswick, Coburg, and Fawkner, she had transformed an overlooked sliver of public land into a garden of native plants—small patches that together became a lifeline for insects.
In cities, green space is precious. But most people don’t think twice about the thin strip of grass between the curb and the footpath. In Melbourne, these nature strips make up over one-third of public green space. For years, they’ve been underused—mowed lawns with little value for wildlife. Now, a simple idea has proven powerful: plant native flowers where there was only grass, and life will come.
Working with the City of Merri-bek and 14 local gardeners, scientists turned theory into data. They recorded insect life before and after planting 14 nature-strip gardens, comparing them to untouched strips nearby. Each garden followed council guidelines, using tough, local plants like common fringe-myrtle and woolly bush—chosen not just for beauty, but for food and shelter they offer pollinators.
The results were clear. The planted strips attracted seven times more pollinating insects than the grass-only ones. They also hosted twice as many different species. That includes native bees, beetles, and butterflies—many of which are specialists, relying on specific plants to survive. One garden might seem small, but 14 of them across a suburb create a network, a kind of stepping stone for insects moving through the city.
This matters because insects are vanishing worldwide. Nearly 90% of flowering plants depend on animals to pollinate them—including crops we eat. And while honeybees get most of the attention, Australia has over 1,500 native bee species alone, plus thousands of moths, butterflies, and beetles, all playing their part. Cities aren’t empty of nature—they can be refuges, if we let them be.
The work wasn’t easy. Clearing weeds and compacted soil took effort. But by autumn planting time, each strip was alive with color and movement. These gardens don’t just help insects—they soften streets, connect neighbors, and remind us that even the smallest patch of land can matter. As cities grow, so does the chance to weave nature back into everyday spaces. A single flower on a sidewalk might seem small. But together, they’re building a wilder, more resilient city—one nature strip at a time.
