Little Spurflower: A Charming Non-Native Ground Cover for Warm Climates
If you’re looking for a low-maintenance ground cover with delicate flowers and aromatic foliage, you might want to get acquainted with little spurflower (Plectranthus parviflorus). This unassuming perennial has quietly made itself at home in parts of the United States, though it’s not originally from around here.
What Is Little Spurflower?
Little spurflower is a non-native perennial forb that belongs to the mint family. True to its name, it produces small, delicate flowers that appear in terminal spikes. The botanical name Plectranthus parviflorus literally means small-flowered, which gives you a pretty good idea of what to expect. You might also see it listed under its synonym, Plectranthus australis.
As a forb, this plant lacks significant woody tissue and stays relatively close to the ground, making it an excellent choice for those looking to fill in bare spots in their landscape.
Where Does It Grow?
Originally from Australia and parts of Southeast Asia, little spurflower has established itself in Florida and Hawaii, where it reproduces on its own and persists without human intervention. It’s essentially become naturalized in these warm, humid environments.
Should You Plant Little Spurflower?
Here’s where things get interesting. While little spurflower isn’t considered invasive or noxious, it is a non-native species that has shown it can spread and persist on its own. This means you’ll want to think carefully about whether it’s the right choice for your garden.
The Pros:
- Low maintenance and drought tolerant once established
- Attractive small white to pale purple flowers
- Aromatic foliage adds sensory interest
- Good ground cover option
- Attracts bees and other small pollinators
The Considerations:
- Not native to North America
- May self-seed and spread beyond where you originally planted it
- Limited to warm climate zones (USDA 9-11)
Native Alternatives to Consider
If you’re leaning toward supporting native ecosystems, consider these native ground covers instead: wild bergamot (Monarda fistulosa) for similar aromatic qualities, or native violets (Viola species) for low-growing coverage with charming flowers. These options will provide better support for local wildlife and pollinators.
How to Grow Little Spurflower Successfully
If you decide little spurflower is right for your garden, you’ll be pleased to know it’s pretty easy to grow.
Growing Conditions:
- Light: Partial shade to full sun
- Soil: Well-draining soil is essential
- Water: Moderate water needs; drought tolerant once established
- Climate: USDA hardiness zones 9-11
Planting and Care Tips:
- Plant in spring after the last frost
- Space plants appropriately to allow for spreading
- Water regularly during establishment, then reduce frequency
- Trim back after flowering to maintain shape and prevent excessive self-seeding
- Monitor for spread and remove unwanted seedlings
The Bottom Line
Little spurflower can be a lovely addition to warm-climate gardens, especially if you’re looking for a low-maintenance ground cover with pollinator appeal. However, as a non-native species, it’s worth considering whether native alternatives might better serve your local ecosystem. Whatever you choose, responsible gardening means monitoring your plants and preventing unwanted spread into natural areas.
Remember, the best garden is one that brings you joy while being mindful of the broader environment. Whether that includes little spurflower or native alternatives is entirely up to you and your garden’s specific needs.
