Mexican Star: A Delightful Native Bulb for Southwestern Gardens
If you’re looking for a charming native plant that brings a touch of elegance to your southwestern garden without demanding much attention, let me introduce you to the Mexican star (Milla biflora). This delightful little perennial bulb is one of those hidden gems that deserves more recognition in native plant gardening circles.





What Makes Mexican Star Special?
Mexican star is a native forb – essentially a non-woody flowering plant that dies back to the ground each year but returns reliably from its bulb. What sets this plant apart is its pristine white, star-shaped flowers that seem to glow against the often harsh backdrop of desert landscapes. The blooms typically appear in late spring to early summer, creating a lovely contrast with the plant’s slender, grass-like foliage.
Where Mexican Star Calls Home
This native beauty is naturally found across the southwestern United States, specifically thriving in Arizona, New Mexico, and Texas. As a true native of these regions, Mexican star has evolved to handle the challenging conditions that come with desert and semi-desert environments.
Why You’ll Want Mexican Star in Your Garden
There are several compelling reasons to consider adding Mexican star to your landscape:
- Drought tolerance: Once established, this plant requires minimal supplemental watering
- Native support: You’ll be supporting local ecosystems and providing habitat for native pollinators
- Low maintenance: Perfect for busy gardeners who want beauty without the fuss
- Pollinator magnet: The flowers attract bees, butterflies, and other beneficial insects
- Versatile size: Compact growth makes it suitable for various garden settings
Perfect Garden Settings
Mexican star shines brightest in:
- Rock gardens and xeriscapes
- Native plant gardens
- Desert-themed landscapes
- Naturalized areas
- Border edges and ground cover applications
This plant works beautifully when mass-planted for a carpet effect or scattered throughout a garden for natural-looking drifts of white blooms.
Growing Conditions and Care
Mexican star is wonderfully adaptable within its preferred growing zones (USDA zones 7-10). Here’s what this easy-going plant needs to thrive:
Sunlight: Full sun is ideal, though it can tolerate some light shade
Soil: Well-draining soil is absolutely essential – this plant cannot tolerate soggy conditions. Sandy or gravelly soils work perfectly
Water: Drought tolerant once established, requiring only occasional deep watering during extended dry periods
Temperature: Hardy in zones 7-10, handling both heat and moderate cold well
Planting and Care Tips
Getting Mexican star established in your garden is straightforward:
- Timing: Plant bulbs in fall for spring blooms
- Depth: Plant bulbs about 2-3 inches deep
- Spacing: Space bulbs 3-4 inches apart for a natural look
- Watering: Water sparingly – overwatering is more harmful than underwatering
- Maintenance: Allow foliage to die back naturally to feed the bulb for next year’s growth
The key to success with Mexican star is remembering its desert origins. When in doubt, err on the side of less water rather than more.
Supporting Native Wildlife
By choosing Mexican star, you’re not just adding beauty to your garden – you’re creating valuable habitat. The flowers provide nectar for various pollinators, including native bees and butterflies that have co-evolved with this plant over thousands of years. This makes Mexican star an excellent choice for gardeners interested in supporting local biodiversity.
Is Mexican Star Right for Your Garden?
Mexican star is an excellent choice if you:
- Live in the southwestern United States
- Want to garden with native plants
- Prefer low-maintenance gardening
- Are creating a drought-tolerant landscape
- Want to support native pollinators
However, if you live outside zones 7-10 or have heavy clay soil with poor drainage, you might want to consider other native alternatives better suited to your specific conditions.
Mexican star proves that native plants can be both practical and beautiful. This little bulb offers the perfect combination of easy care, ecological benefits, and charming blooms that make any southwestern garden feel more connected to its natural surroundings.
