Plant Swap Program

Help protect our native ecosystem by swapping out your invasive, fire prone fountain grass for native, pollinator friendly desert milkweed!

This project is funded by the Arizona Department Forestry and Fire Management Invasive Plant Grant.

Project Purpose

Fountain grass is an invasive species originally from Africa that was brought to the United States for ornamental and erosion control purposes. It has since become an issue throughout the Sonoran Desert as it outcompetes native plants, creating a monoculture, and acts as fuel to wildfires. Fountain grass has been added to the Arizona Noxious Weed List as of 2020.

Desert milkweed is a critical native plant for pollinators, especially monarchs and provides similar aesthetic properties as fountain grass.

The project areas we selected border open spaces and we hope that by removing fountain grass in the surrounding neighborhoods, we will be able to reduce creep into the open spaces themselves.

How to Participate

Participating is as easy as 1, 2, 3!

Register for the program using the link below!

2. Remove

Once you receive confirmation from CAZCA that you are registered, remove your fountain grass, take photos (before and after) and send them to CAZCA, and then dispose of it properly (bagged so it won’t continue to spread seed)!

3. Receive and Replace

Receive your FREE desert milkweed and plant it in your yard to replace your fountain grass!
