Sempervivum If you’ve got boulders in the back forty or a rocky sandy sun-drenched spot in the dooryard, you have the makings for an amazing cascading Sempervivum display.
Sempervivum means ‘always alive.’ Low-growing rosette-forming succulents produce runners and babies by the boatload. Drought- and heat-tolerant beyond belief, and cold-hardy, too!
Sempervivums offer up a fun way to learn about fractals and how our world works—you can plant them in a strawberry pot with the kids for a fun easy-to-care for botany/math project, or go whole hog and build a mini-boulder palace all decked out in Hens and Chicks and mosses.
Performs best in super-drained gravelly soil with lots of sun and dappled shade. We’re offering a mix of varieties including reds, greens and purples. Z3. (2½" pots)

Herbaceous Perennial Plants
When you receive your order, open the bags and check the stock. Roots and crowns should be firm and pliable. If they are slightly dry, add a little water or, if they are going to be potted up soon, wet the roots. Generally, a little surface mold is harmless and will not affect the plant’s future performance. If you cannot pot them up immediately, store them in a cool (35–40°) location for a short time.
Do not plant bare-root perennial plant crowns directly outdoors.
Pot up the rootstock using well-drained potting mix in a deep 6" pot or a 1-gallon container. Avoid coiling the roots in under-sized containers. Grow newly potted perennials for a few weeks in a protected location in indirect light at 50–60°. Wet and/or cold conditions for an extended period may cause rotting. Transplant outside once they show some top growth and the danger of frost has passed.
