Sedum sarmentosum has succulent, evergreen leaves atop arching, low-lying stems. Yellow flowers with five petals arise on inflorescences during the summer.
Like most succulents, it doesn’t like wet feet and is likely to rot in soggy soil. Dig in a generous amount of sand or grit to improve drainage. Keep the soil moist for a few weeks, or until stringy stonecrop is established. Thereafter, this groundcover is drought-tolerant, but benefits from occasional irrigation during hot, dry weather.
Plant stringy sedum groundcover in full sun or partial shade, as long as the plant receives at least six hours of sunlight per day.
Fertilize your sedum groundcover once or twice during the growing season using a low-nitrogen fertilizer, if needed.
