Sempervivum, Jovibarba houseleek

Houseleek is in fact a plant of two genus - sempervivum and jovibarba. They are so similar that the trade does not really differentiate them, possibly also because sempervivum is an accepted synonym for jovibarba. Houseleek comes from mountainous regions of Asia, Central Russia, and almost all Europe. It is an evergreen, thick-leaved succulent with handsome rosettes of coloured foliage. Several species and numerous varieties and hybrids are known, many of them combining shades of green, silvery blue, various depths of red, even pink and burgundy red. Multicoloured forms are very popular as well as hairy types (s.arachnoideum - these dislike winter wet). From midsummer summer they make star-shaped flowers of pale colours (white, yellow, red, or purple) on very thick, 5-20 cm tall stems, but some produce flowers just above the foliage like e.g. ice plants. Rosettes die after flowering but are quickly replaced by others that were formed meanwhile (just like very similar century plants).

Houseleek is so easy to grow. Just place your plant into gritty, sharp-draining soil in full sun and enjoy its happy life. No other needs. Fertilizing is possible if you want bigger plants and quicker spreading but is not necessary. Plants spread slowly by producing new spherical babies on thin wires which dry out as soon as the new plant touches the soil and is big enough to make its own roots. Houseleek is very hardy to about -34°C (USDA zone 4), though some species and varieties may be hardier or a little more tender than others.

Apart from specialist growers and collectors the current trade practise of most European suppliers is such that plants are sold in mixed trays, often without variety names. In order to differentiate them here, we list them by colour attaching a photograph of each plant so you can see what we are selling, and you can make an order for exactly the plant you want and see in the picture.
