Sempervivum Calcareum


Sempervivum calcareum, also known as Houseleek, is a succulent perennial plant that can reach 6 inches (15 cm) tall. Its rosettes are beautifully symmetrical with a dome shape. The leaves are blue-green and have pointy burgundy tips. Sempervivum calcareum forms dense mats by multiplying via short-stalked offsets. In summer, some mature rosettes produce clusters of starry, yellow-eyed, light pink flowers on thick stalks. The rosettes that flower will naturally die afterwards, but by this time, the plant has likely produced many offsets that will continue to grow. 

Soil: Gritty soil, Sandy

Light: Full Sun or Partial shade

Water: Water thoroughly when soil is dry to the touch, then let drain completely. Reduce watering to a minimum during winter. 

Temperature: Prefers warm summer temperatures (65ºF/18ºC – 70ºF/21ºC). In winter, it can tolerate temperatures down to freezing.

Fertilizer: Feed with a controlled-release fertilizer at the beginning of the growing season.

Your plant will be meticulously bubblewrapped and shipped in a sturdy box. Most 2" plants are shipped in their original plastic pot with soil. Fragile and big 4" plants are shipped bareroot to ensure their safety. When opening your package, some soil may be loose in the box. Plant orders are shipped within 3-5 days depending on availability of the plant. We ship our plants Monday through Friday, all twelve months of the year! If you need your order urgently, please message us so we can upgrade your shipping (additional cost applied).

Here is our blog about the shipping process and packaging

We do not ship outside of the continental United States. 

We only ship out beautiful, healthy plants! Please track your package and open it immediately upon arrival. If you receive your package and are not satisfied, please message us immediately. Fragile plants such as bearpaw, baby toe, etc. may break or loose a few of their leaves during transport. Please contact us for replacements if your plants are severely damaged. We'll try our best to accommodate you. 

Plants may be slightly larger or smaller than the pot they are grown in, depending on availability or time of year. Sedums such as Cherry Tart and Lime Zinger are dormant in the winter, i.e. they wilt, start dropping leaves, and look dead. It's simply a survival mechanism that help succulents stay alive over the cold winter and gear up for warmer days ahead.

Provide porous soil with adequate drainage, pots with drainage hole are recommended. Bright, filtered light and ample airflow. Water thoroughly when soil is dry to the touch. Never let your succulents sit in water. Do NOT water on the leaves. If you water from beneath by letting the plant sit in a saucer of water, make sure to pour off any excess water after a few minutes.

The hotter it is outside, the faster your soil will dry out, so you’ll need to water more often if you live in a hot area. Water with caution in winter, as the plant can lose its roots if the soil stays cold and wet for extended periods; protect from frost to prevent scarring.

Sempervivum Calcareum

My experience was great. Being a new succulent owner, I've learned to not go cheap and buy the larger sizes as I think for beginners, (or at least me) I will have an easier time keeping them alive after transplanting. My plan is to give them as Christmas gifts so I bought the subscription plant box as well. Thanks so much for the great planting directions and for sending them with such care!

Great selection of succulents, thank you.

Would be nice if the shipment card came with the species names so I could be sure of where to plant them - full sun or part sun.

So symmetrical!

I ordered three total and this one came in the best. Looks pretty much as pictured and it's beautiful!
