Jovibarba ("beard of Jupiter") is a small genus of three species of succulent flowering plants in the family Crassulaceae, endemic to mountainous regions in the southeastern quadrant of Europe. The genus is sometimes classified as a subgenus of Sempervivum , to which it is closely related. Jovibarba have pale-greenish-yellow or yellow actinomorphic flowers with about six petals, while Sempervivum have generally pinkish flowers with around twice as many petals, which open more widely than jovibarba flowers. The common name hen and chicks is applied to some Jovibarba species (and also species in several other genera).

Contents

Most jovibarbas, like sempervivums, reproduce via offsets in addition to producing seeds via sexual reproduction. Jovibarba heuffelii [1] does not produce offsets on stolons. Instead the offspring of this plant are produced within the mother plant. To propagate it must be split with a knife. The other two jovibarba species are commonly called rollers. They produce offsets that are lightly attached and easily pop off and roll away from the mother plant. Offsets survive the main rosette, which is monocarpic.

Species

Only three species are accepted as distinct by the Flora Europaea:

Jovibarba globifera and its subspecies (subsp. hirtum, subsp. allionii, subsp. arenaria) live in the eastern and southern Alps, the Carpathians and the western Balkans south to northern Albania. J. heuffelii occurs in the remainder of the Balkans and the eastern Carpathians, southeast of J. globifera. J. hirta occurs further west, in the southwestern Alps.

Crassulaceae Family of flowering plants

The Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic.

<i>Sempervivum</i> Genus of flowering plants in the family Crassulaceae

Sempervivum is a genus of about 40 species of flowering plants in the family Crassulaceae, commonly known as houseleeks. Other common names include liveforever and hen and chicks, a name shared with plants of other genera as well. They are succulent perennials forming mats composed of tufted leaves in rosettes. In favourable conditions they spread rapidly via offsets, and several species are valued in cultivation as groundcover for dry, sunny locations.

Hellebore Genus of plants

Commonly known as hellebores, the Eurasian genus Helleborus consists of approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae, within which it gave its name to the tribe of Helleboreae. Despite names such as "winter rose", "Christmas rose" and "Lenten rose", hellebores are not closely related to the rose family (Rosaceae). Many hellebore species are poisonous.

<i>Dasiphora fruticosa</i> Species of flowering plant in the rose family Rosaceae

Dasiphora fruticosa is a species of hardy deciduous flowering shrub in the family Rosaceae, native to the cool temperate and subarctic regions of the northern hemisphere, often growing at high altitudes in mountains. Dasiphora fruticosa is a disputed name, and the plant is still widely referenced in the horticultural literature under its synonym Potentilla fruticosa. Common names include shrubby cinquefoil, golden hardhack, bush cinquefoil, shrubby five-finger, widdy, and kuril tea.

Hen and chicks Hens of chicks

Hen and chicks is a common name for a group of small succulent plants, a term that indicates a plant that possesses enlarged parts to store water. It belongs to the flowering plant family Crassulaceae, native to southern Europe and northern Africa. The plants grow close to the ground with leaves formed around each other in a rosette, and propagating by offsets. The "hen" is the main, or mother, plant, and the "chicks" are a flock of offspring, which start as tiny buds on the main plant and soon sprout their own roots, taking up residence close to the mother plant.

<i>Helianthemum</i> Genus of flowering plants in the rock rose family Cistaceae

Helianthemum, known as rock rose, sunrose, rushrose, or frostweed, is a genus of about 110 species of flowering plants in the family Cistaceae. They are widely distributed throughout the Northern Hemisphere, especially in the Mediterranean.

<i>Saxifraga stellaris</i>

Saxifraga stellaris, the starry saxifrage or hairy kidney-wort, is an Arctic–alpine species of saxifrage. It produces panicles of 5–10 white flowers on a stem up to 20 cm (7.9 in) tall, rising from a basal leaf rosette. One subspecies is found from eastern Canada to Russia, including the British Isles, while another is found in the mountains of southern Europe.

<i>Campanula glomerata</i> Species of plant

Campanula glomerata, known by the common names clustered bellflower or Dane's blood, is a species of flowering plant in the genus Campanula, belonging to the family Campanulaceae. It is the county flower of Rutland, England.

<i>Dactylis glomerata</i> Species of grass

Dactylis glomerata, also known as cock's-foot, orchard grass, or cat grass (due to its popularity for use with domestic cats) is a common species of grass in the genus Dactylis. It is a cool-season perennial C3 bunchgrass native throughout most of Europe, temperate Asia, and northern Africa.

<i>Sempervivum arachnoideum</i> Species of succulent

Sempervivum arachnoideum, the cobweb house-leek, is a species of flowering plant in the family Crassulaceae, native to European mountains, in the Alps, Apennines and Carpathians. Growing to 8 cm (3 in) tall by 30 cm (12 in) wide, it is a rosette-forming succulent perennial, valued in cultivation for its ability to colonise hot, dry areas via offsets.

<i>Dianthus superbus</i> Species of flowering plant

Dianthus superbus, the fringed pink or large pink, is a species of Dianthus native to Europe and northern Asia, from northernmost Spain and France north to arctic Norway, and east to Japan; in the south of its range, it occurs at high altitudes, up to 2,400 m.

<i>Aconitum napellus</i> Species of plant

Aconitum napellus, monk's-hood, aconite or wolfsbane, is a species of highly toxic flowering plant in the genus Aconitum of the family Ranunculaceae, native and endemic to western and central Europe. It is an herbaceous perennial plant growing to 1 m tall, with hairless stems and leaves. The leaves are rounded, 5–10 cm (2.0–3.9 in) diameter, palmately divided into five to seven deeply lobed segments. The flowers are dark purple to bluish-purple, narrow oblong helmet-shaped, 1–2 cm (0.39–0.79 in) tall. Plants native to Asia and North America formerly listed as A. napellus are now regarded as separate species. The plant is extremely poisonous in both ingestion and body contact.
