California amaranth is a native annual forb that grows 1 to 3 feet tall with an upright, bushy form. It produces small, dense flower clusters in summer and fall that attract beneficial insects. This drought-tolerant plant thrives in full sun locations with minimal water once established.
In an HOA neighborhood
California Amaranth takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.

Wildlife value
The dense flower clusters provide nectar for bees and beetles during the summer blooming period. Seeds may also attract small birds later in the season.
