I've had this sedum plant for nearly 20 years now. It was growing here when we moved into the house. I transplanted some of it into this planter box and it has thrived with almost no care from me except infrequent watering in summertime dry spells. It's a sedum that flowers in August and September. One French name for it is orpin, and in English it's called stonecrop. Right now, It's about ready to burst into bloom.
