Sempervivum is a genus of approximately 40 species of the Crassulaceae family and thousands of hybrid cultivars. They are a very ornamental, drought tolerant, sun loving plant that does well in full sun or partial sun depending on your climate and weather conditions.

Common names are Hen and Chicks and Houseleeks

They are rosette forming hardy succulent plants, most of which will grow in USDA zone 4 and up. They are of European origin, found in mountain, subalpine and alpine belts throughout Europe. Sempervivum are a monocarpic perennial. They live for several years producing offsets before blooming. Once a rosette blooms it will die, hopefully leaving behind many offsets to replace her.

The blooms of Sempervivum can be quite beautiful, and occasionally I find one that has a slight fragrance. The flower colors range from varying shades of pink, red, white (seldom) and even a very pale yellow/green. They are star shaped with seven or more petals. Bees and butterflies are drawn to the blooms during the warm summer days.
Flowers are hermaphrodite, having first a male stage. Then the stamens curve themselves and spread away from the carpels at the center of the flower, so self pollination is difficult.

Caring for Seedlings

JungleShadows said:
On the seedlings I use "Quick Start" every two weeks and then taper off about August so they are more ready for winter. The named varieties I usually only fertilize in the spring but last year I did push the ones received in '12 from Fernwood so they would be big clumps in '14. Big mistake! They were pushed too hard and had losses from too lush plants facing the freeze in December. Of course in a "normal" year in Oregon that wouldn't have been a problem! Kevin
