If you’re looking to add a touch of wild western charm to your garden, Torrey’s blazingstar (Mentzelia torreyi var. acerosa) might just be the hidden treasure you’ve been searching for. This remarkable biennial forb brings something truly special to native plant gardens with its stunning evening display of golden, star-shaped blooms that seem to light up the twilight hours.
A True Western Native
Torrey’s blazingstar is a proud native of the American West, specifically calling Idaho home. As a plant that’s perfectly adapted to the challenging conditions of western landscapes, it represents the resilient beauty of our native flora. However, there’s something important every gardener should know about this species.
Important Conservation Note
Before you fall completely in love with this plant (and trust us, you will), it’s crucial to understand that Torrey’s blazingstar has a global conservation status of S4T3, indicating it has some conservation concerns. This means if you choose to grow this beauty, you should only source it from reputable native plant nurseries that practice responsible propagation. Never collect seeds or plants from wild populations.
Why Choose Torrey’s Blazingstar?
This isn’t your typical garden flower, and that’s exactly what makes it so appealing:
- Evening Magic: The large, papery yellow flowers open in the evening, creating a spectacular nighttime display
- Pollinator Paradise: Night-flying moths, beetles, and other nocturnal pollinators absolutely adore these blooms
- Drought Champion: Once established, this plant thrives with minimal water
- Native Heritage: Supporting local ecosystems and wildlife

Perfect Garden Settings
Torrey’s blazingstar isn’t meant for every garden, but it absolutely shines in the right setting:
- Native plant and wildflower gardens
- Xeriscaping and drought-tolerant landscapes
- Rock gardens and naturalized areas
- Evening or moon gardens
- Pollinator-focused plantings
Growing Torrey’s Blazingstar Successfully
As a biennial, this plant has a two-year life cycle, spending its first year developing roots and foliage, then blooming magnificently in its second year before setting seed. Here’s how to give it the best chance to thrive:
Ideal Growing Conditions
- Sunlight: Full sun is absolutely essential
- Soil: Well-draining sandy or rocky soils work best
- Water: Drought tolerant once established; avoid overwatering
- Climate: Adapted to USDA zones 4-8
Planting and Care Tips
- Seeding: Direct seed in fall for best results
- Spacing: Give plants room to develop their natural form

Is Torrey’s Blazingstar Right for Your Garden?
This plant is perfect for gardeners who appreciate native flora, want to support nocturnal pollinators, and don’t mind waiting for the spectacular second-year bloom show. It’s ideal if you’re creating a low-maintenance, drought-tolerant landscape that celebrates regional plant heritage.
However, it might not be the best choice if you prefer plants with immediate gratification, need year-round foliage, or garden in very humid conditions where well-draining soil is hard to achieve.
A Responsible Choice
By choosing to grow Torrey’s blazingstar with responsibly sourced material, you’re not just adding beauty to your garden – you’re participating in conservation efforts and helping maintain genetic diversity of this special native plant. It’s a small but meaningful way to support our native plant heritage for future generations.
