Growing Hartweg’s Sundrops Successfully
The best part about growing this native gem? It’s refreshingly easy! Here’s what you need to know:
Location and Soil

Hardiness
This tough perennial thrives in USDA hardiness zones 5-9, making it suitable for a wide range of climates from the northern plains down to the hot Southwest.
Planting and Care Tips
- Watering: Water regularly the first growing season to establish roots, then reduce to occasional deep watering
- Fertilizing: Skip the fertilizer – this native prefers lean soils
- Maintenance: Minimal pruning needed; may self-seed in favorable conditions
- Spacing: Allow room for the plant to spread as ground cover
Supporting Your Local Ecosystem
By choosing Hartweg’s sundrops, you’re doing more than just adding pretty flowers to your garden. Native plants like this one support local pollinator populations and contribute to healthy, sustainable landscapes. The bright yellow blooms provide nectar for native bees and butterflies, while the plant itself fits naturally into regional ecosystems.
Is Hartweg’s Sundrops Right for Your Garden?
This native wildflower is an excellent choice if you:
- Live in its native range (Southwest and south-central United States)
- Want a low-maintenance, drought-tolerant plant
- Love supporting native pollinators
- Enjoy long-blooming flowers
- Need ground cover for sunny, dry spots
However, you might want to look elsewhere if you have consistently moist soil or heavily shaded areas, as this sun-loving native won’t thrive in those conditions.
Hartweg’s sundrops proves that native doesn’t mean boring – sometimes it means discovering a cheerful, easy-care plant that’s been thriving in your region long before any of us started gardening. Give this sunny native a try, and you might just find yourself with a new favorite wildflower!
