Do that in a city that doesn’t care about bicycles, and the plants will be trimmed literally never.
I’ve seen it too often. You get one person to install a bike lane. It’s a major win. But the city doesn’t consider it real infrastructure, so they just ignore it and never maintain it.
Problem with the plants is that eventually they become a hazard for bicycles. Best not to put something there that requires weekely maintenance
You can have slow-growing hedges at a slight distance (~0.5 m to 1 m) from the path, or the plants could be in boxes.
Something like this is also possible:
The hedges typically don’t really require weekly maintenance - once every few months suffices.
Alternatively, trees could be used, with grass and flowers inbetween.
