Wow! Do you happen to know what flowers you've got planted there?
I would love to do similar. So far I've been doing lots of clover and putting in crocus bulbs randomly.
I didn't plant them, they grow like crazy and destroy the grass :D I don't know what they're called, but I could try one of those plant identification apps. Check back in a few days, I'll try to post a comment if I find out more.
