I live in Riverside, California (halfway between Los Angeles and Palm Springs).
In the front of my house, I have a 30' by 20' garden containing about a dozen roses and other shrubs.
Years ago, I planted gazanias as a groundcover but they now unattractively thin, lanking and gangly.
I'd like to replace the gazanias with an attractive groundcover that flowers more-or-less continuously.
There won't be any foot traffic but I want a low-growing ground cover that won't overwhelm the shrubs in my garden and that will prevent the weeds.
