50 JOVIBARBA HEUFFELII SEEDS- HARDY SUCCULENT,Hens and Chicks, Houseleek.
Jovibarba heuffelii is a genus of alpine suculents in the Crassulaceae family closely resembling Sempervivum. Their natural habitat is the Balkans and Eastern Carpathians. The plants seem distinct from Sempervivum, however botanically it remains an uncertainty. They are hardy to USDA zone 4.

In the spring, sow the dust like seeds in shallow trenches in an open flat filled with sterile soilless mix such as Sunshine Mix #4 or Pro Mix, don’t cover the seed and mist lightly until they germinate. An alternate method to try is winter sowing, with nature doing most of the work.
A dome or clear cover can help keep the air around the germinating seeds humid – dump off any condensation from the inside of the cover as the large droplets that form can induce rotting in the seedlings. Take the cover off in stages: one week after most of the seeds have germinated, take the cover off for a few hours each day, then a week later take it off all day, then off entirely.
This gradual change in humidity will 'harden off' the seedlings until they can face the harsh world outside. A similar change into brighter light will encourage robust hardy growth, as will a reduction in moisture.
