Jovibarba
Those Unusual
and Underused Hardy Succulents
Jovibarba are sometimes called the other hens and chicks.They are very similar in appearance and culture to Sempervivum as they both resemble a rose in form; the most obvious difference is the way the 'chicks' form. Only three species are accepted as distinct by the Flora Europaea: - Jovibarba globifera (syn. J. sobolifera; Sempervivum globiferum)
- Jovibarba heuffelii (syn. J. velenovskyi; Sempervivum heuffelii)
- Jovibarba hirta (syn. Sempervivum hirtum)
Jovibarba globifera and its subspecies (subsp. hirtum, subsp. allionii, subsp. arenaria) originate in the eastern and southern Alps, the Carpathians and the western Balkans south to northern Albania. Jovibarba heuffelii occurs in the remainder of the Balkans and the eastern Carpathians, southeast of Jovibarba globifera. Jovibarba hirta occurs further west, in the southwestern Alps. Apparently, just to add to the confusion the Jovibarba have now been returned to their original genus of Sempervivum. As is customary with the naming of plants, both names will be in general use. Sempervivum chicks are attached under the hen rosette, but many Jovibarba species such as allionii, sobolifera and hirta hold them over top of the adult plant on delicate brittle stems which break easily, making it possible for the chick, or 'propagule', to roll away to find a place to root, giving rise to their other name of 'rollers'. Learn more about how to grow Jovibarba species here. Jovibarba heuffelii are another thing entirely, splitting the crown of each rosette into two or more new crowns. They must be surgically separated to form new plants, and as a consequence tend to be more expensive. Find out all about how to grow Jovibarba heuffelii with details about propagating them. The other major difference between Sempervivum and Jovibarba is that the flowers are tiny downward or outward facing bells rather than upturned star shaped blooms. Jovibarba heuffelii in bloom | After the bloom has finished, the rosette dies. This is called 'monocarpic' or once-blooming. Seed propagation is one way to get lots of new plants - collect the drying seed pods after the plant flowers and place them in a paper bag, or seek out seeds online from specialty seed houses. How to Use Jovibarba Plant among the stones in a rock wall, or as succulent groundcovers in your xeric garden in a tapestry bed. Rock gardens and crevice gardens are fabulous planted with a single species or a mix of the many varied forms of these fascinating plants. As they spread, the textures and colours become more and more beautiful, like an antique quilt. one of the many forms of Jovibarba heuffelii | a golden form of Jovibarba heuffelii |
All these species are little known except to collectors, but I'd like to change that as I'm fascinated by the form and tenacity of these drought smart plants. Maybe you feel the same way and would like to grow some of these unusual, colourful and rare hardy succulents in your xeric garden.
