Sedum lydium is an adorable densely growing green groundcover. It'll get tiny white flowers that butterflies love!
It requires full sun and when planted in the ground it is cold hardy to -20F. All the growth above the soil dies off in winter. In spring, the plant puts out new growth multiplying each year.
Grows 2-4" tall. Plant 8-12" apart to give room for it to spread.
Allow for soil to fully dry between watering.
