Purplemat: A Charming Native Ground Cover for Desert Gardens
If you’re looking for a low-maintenance, drought-tolerant ground cover that’s as tough as it is pretty, let me introduce you to purplemat (Nama demissum var. demissum). This delightful little native plant might not be the showiest flower in the garden, but it’s got character and staying power that makes it a real gem for the right setting.
What is Purplemat?
Purplemat is a native annual forb that forms lovely low mats of foliage topped with clusters of small purple to lavender flowers. As an herbaceous plant, it doesn’t develop woody stems but instead grows as a soft, low-spreading ground cover. Don’t let its diminutive size fool you – this little plant is perfectly adapted to some of the toughest growing conditions in the American Southwest.
Where Does Purplemat Come From?
This charming native calls the southwestern United States home, naturally occurring across Arizona, California, Nevada, and Utah. You’ll find it thriving in desert environments where many other plants would struggle, making it a true testament to the beauty and resilience of our native flora.
Why Grow Purplemat in Your Garden?
There are several compelling reasons to consider adding purplemat to your landscape:
- Water-wise gardening: Once established, purplemat requires minimal irrigation, making it perfect for drought-conscious gardeners
- Native plant benefits: Supporting local ecosystems by growing plants that naturally belong in your region
- Pollinator support: The small flowers attract native bees and other beneficial insects
- Low maintenance: As an annual, it completes its life cycle naturally without requiring pruning or deadheading
- Unique texture: The mat-forming growth habit adds interesting ground-level texture to garden designs
Perfect Garden Settings for Purplemat
Purplemat shines in specific garden styles where its natural characteristics can be appreciated:
- Desert gardens: Right at home among cacti, agaves, and other desert natives
- Rock gardens: Excellent for tucking between stones and boulders
- Xeriscaping projects: A natural choice for water-conservation landscaping
- Native plant gardens: Perfect for recreating natural southwestern plant communities
Growing Conditions and Care
The beauty of purplemat lies in its simplicity. This plant thrives in conditions that would challenge many garden favorites:
- Sunlight: Full sun exposure – the more, the better
- Soil: Well-draining sandy or rocky soils; avoid heavy clay or water-retentive soils
- Water: Drought tolerant once established; overwatering can actually harm the plant
- Climate zones: Best suited for USDA hardiness zones 8-10
Planting and Care Tips
Growing purplemat successfully is refreshingly straightforward:
- Timing: Direct seed in fall for best results, allowing natural winter chill to break dormancy
- Soil preparation: Ensure excellent drainage – amend heavy soils with coarse sand or gravel if needed
- Watering: Water sparingly during establishment, then rely mainly on natural rainfall
- Fertilizing: Generally unnecessary – these plants are adapted to lean soils
- Maintenance: Minimal care required; simply allow the plant to complete its natural cycle
Is Purplemat Right for Your Garden?
Purplemat is an excellent choice if you live in the southwestern United States and want to create a water-wise garden that supports native wildlife. It’s particularly valuable for gardeners who appreciate subtle beauty over flashy displays and want plants that work with, rather than against, their local climate.
However, this plant might not be the best fit if you’re gardening outside its native range, prefer lush green landscapes, or want showy flowers that make a bold statement. Remember, as an annual, purplemat will complete its life cycle within one growing season, so plan accordingly in your garden design.
For southwestern gardeners committed to sustainable, water-wise landscaping, purplemat offers a wonderful opportunity to grow a truly local plant that connects your garden to the natural heritage of your region. Sometimes the most rewarding plants are the humble natives that have been quietly thriving in your area for centuries!
