In an HOA neighborhood
California Stinkweed 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.
- Very small size makes it appear weedy
- Annual nature means gaps in coverage
- Spiky, irregular growth habit looks unmanicured
