I think there are a few varieties of ice plant, some don’t grow into the mounds or flower as much, the one that kinda grows diagnonally is pretty cool and doesn’t go brown in summer. I dig the kind that looks like purple snow a few weeks a year, imo, they beat red apple which tends to overgrow. Like the others said, these types of ground cover are common because they do well in heat, use little water and make for a great fire break.
Do your best to avoid POMPUS GRASS, I can’t believe they even sell it at home depot because it is a weed and not native, that is a rat paradise and a fire hazzard. Plus it’s near impossible to get rid of without nuclear weapons, I think it uses round-up like plant food and it spreads like crazy, try to cut it and it will cut you back with it’s razor sharp leaves. The last time I battled one I swear it said “feed me seymore.”
