The Hahamongna Native Plant Nursery is dedicated to promoting pollinator and wildlife habitat growth one yard at a time! We specialize in California native plants, many found and propagated right here in the Arroyo Seco watershed. 
 
Numerous California native plants and trees are endemic (naturally occurring and unique to this area) and have evolved to thrive in the Southern California climate. They can subsist on the water and soil naturally available with minimal additional input, reducing the need for excessive watering and fertilizers.
 
Landscaping with native plants provides optimal food and habitat for wildlife while at the same time minimizing negative ecological impacts.

Unsure what is adapted to grow in your area? Calscape is a great resource with pictures, general description, native range, condition requirements, and wildlife supported.  You can look up individual plants or use their garden planner tool for landscaping suggestions based on your location and aesthetic preferences!
