Sedum rupestre ‘Blue Spruce’ 

Sedum Blue Spruce

Another fast, low growing, stonecrop ground cover that takes heat drought and poor-soil. It grows to 8″ and thrives on neglect. Later this summer I will show you the masses of bright yellow flowers. I am less enamored with the yellow bloom than the blue color so I often pinch or shear them back to delay their bloom. My preference is to see a low-growing mat, but by August or September I have had it with pinching back so I let it bloom. Blooming or not it could not care less if it is 100+ degrees. All stonecrops prefer well-drained soil and I usually add sand to the planting area, but this Sedum seems less particular than most so if you are a new gardener get it! USDA Zones 3-9.
