Sempervivum arachnoideum - Cobweb Description
Pique curiosity with cobweb hens and chicks (Sempervivum sp.)! It looks for all the world like a colony of magical spiders spun dazzling webs over the plants, but in fact, the white hairs are a form of natural drought resistance that make this plant practically indestructible. We especially like to set off cobweb hens and chicks by placing them among dark colored succulents, like purple or red sedum, which makes the white fuzz pop even more.

Soil: Very well-drained, even dry, soil is imperative for success with hens and chicks. Nothing will do them in faster than soggy conditions, so plant only in soils that are never wet for any lengthy period of time. Little volume of soil is needed; sempervivum will grow in rocky crevices, cracks, walls, between paving stones, and in shallow containers.
Light: Full sun - at least 6 hours/day - is recommended. Very light shade may be okay in hot climates.
Water: Immediately after transplanting, water generously. After that let the soil dry out between watering. Once established, sempervivum is very drought tolerant, requiring little to no supplemental watering.
Spacing: 6" - 12" to start - plants will soon fill in and knit together.
Fertilizing: None needed.
Winterizing: No special care needed.
Maintenance & pruning: Once a hen plant produces a chick, that chick will begin creating its own chicks the following year. Large hen plants eventually grow a tall flower stalk and die after blooming. However, this is no cause for concern as by the time it does this, it will have left behind a large colony of chicks to take its place. Cutting off the center stalk will not prevent the plant from dying. Chicks can be left in place or plucked out and relocated to expand your display.
