If you want to win over neighbors with your front yard wildlife garden (or at least not totally cheese them off) while avoiding county weed control, there are a few key strategies to take:
1) Do not just let your lawn or landscape "go."
2) Create structure in garden beds and the landscape. That can most easily mean plant tiers -- short stuff in front, tall stuff in back or in the middle.
3) Plant flowers in masses or drifts. 3 or 5 of a kind together. Do not just toss a bag of seed out there.
4) Have a mulch or lawn pathway that's plenty wide and accessible. This helps frame the landscape and welcomes folks in.
5) Don't let plant material droop onto sidewalks or driveways or impede viewing angles at street corners.
6) Include a bench or table or sitting area.
7) Keep it weeded. Thin seedlings that could get out of hand (hello, Rudbeckia) and to maintain tiers / massing, aka the designed or intentional look. You don't have to go crazy doing this, just a little TLC can go a long way.
8) Be able to name every single plant in your landscape using the common AND Latin names. Using the Latin name helps you come off as an authority (which you should be, anyway) to both neighbors and weed ordinance folks.
All that being said, if you're like me you take even more risks in the backyard behind the fence. Case in point:
