Do you have a picture of what it looks like in full display? I have been thinking of trying clover on mine.
I normally don't cut the grass until it's long enough that I can pick the flowers there and bring them inside (monthly?)
My real goal is to provide a maximally inhospitable environment for cockroaches of all sizes.
Though it's really just the grass and dandelions that grow tall. If I had my way, I'd kill all the grass and just throw out wild violets and clover. So much prettier, and requires way less maintenance.
Currently in the process of finding a house, and specifically avoiding HOAs. They'd never let something like this fly, which IMO should be illegal(not your yard, rules banning something like your yard).
