Hypericum is a genus of flowering plants in the family Hypericaceae. The genus has a nearly worldwide distribution, missing only from tropical lowlands, deserts and polar regions. Many Hypericum species are regarded as invasive species and noxious weeds. All members of the genus may be referred to as St. John's wort, and some are known as goatweed. The white or pink flowered marsh St. John's worts of North America and eastern Asia are generally accepted as belonging to the separate genus TriadenumRaf.
Cyclamen is a genus of 23 species of perennial flowering plants in the family Primulaceae. In English, it is known by the common names sowbread or swinebread. Cyclamen species are native to Europe and the Mediterranean Basin east to the Caucasus and Iran, with one species in Somalia. They grow from tubers and are valued for their flowers with upswept petals and variably patterned leaves.
A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. Storage organs often grow underground, where they are better protected from attack by herbivores. Plants that have an underground storage organ are called geophytes in the Raunkiær plant life-form classification system. Storage organs often, but not always, act as perennating organs which enable plants to survive adverse conditions.
Hedera hibernica, the Atlantic ivy, Boston ivy or Irish ivy, is a species of ivy native to the Atlantic coast of Europe.
Hedera helix, the common ivy, European ivy, or just ivy, is a species of flowering plant in the family Araliaceae. It is native to most of Europe and parts of western Asia. Ivy is a clinging evergreen vine that grows on tree trunks, walls, and fences in gardens, waste spaces, and wild habitats. Ivy is popular as an ornamental plant, but escaped plants have become naturalised outside its native range. Ivy has considerable cultural significance and symbolism.
Cyclamen cyprium is a perennial growing from a tuber, native to woodland at 300–1,200 m (980–3,940 ft) elevation in the mountains of Cyprus. It is the national flower. Cyclamen persicum and Cyclamen graecum are also found on Cyprus, but are not endemic.
Cyclamen graecum, the Greek cyclamen, is a perennial plant in the flowering plant family Primulaceae that grows from a tuber. It is native to southern Greece and Crete, and is prized for its variable leaf forms, which include some of the most striking of any cyclamen.
Pelargonium peltatum is a scrambling perennial plant with five shallow or deeply lobed, circular- to heart-shaped, somewhat fleshy leaves, sometimes with a differently coloured semicircular band, that has been assigned to the cranesbill family. It carries umbel-like inflorescences with 2–10, white to mauve, bilateral symmetrical flowers, each with a "spur" that is merged with the flower stalk. It is known by several common names including ivy-leaved pelargonium and cascading geranium. It is native to the Cape Provinces of South Africa. In its home range, it flowers year round but most vigorously from August to October.
Cyclamen purpurascens, the purple cyclamen, is a species of flowering plant in the genus Cyclamen of the family Primulaceae, native to central Europe, northern Italy, and former Yugoslavia. It is an evergreen tuberous perennial with (usually) variegated leaves, and deep pink flowers in summer.
Cyclamen coum, the eastern sowbread, is a species of flowering plant in the family Primulaceae. It is a tuberous herbaceous perennial, growing to 5–8 cm (2–3 in), with rounded heart-shaped leaves and pink shell-shaped flowers with darker coloration at the base. It is valued in horticulture as groundcover, and for the flowers which bloom in winter and early spring.
Cyclamen persicum, the Persian cyclamen, is a species of flowering herbaceous perennial plant growing from a tuber, native to rocky hillsides, shrubland, and woodland up to 1,200 m (3,900 ft) above sea level, from south-central Turkey to the Levant. It also grows in Algeria and Tunisia and on the Greek islands of Rhodes, Karpathos, and Crete, where it may have been introduced by monks. Cultivars of this species are the commonly seen florist's cyclamen.
Cyclamen cilicium is a species of flowering perennial plant in the family Primulaceae. It is native to coniferous woodland at 700–2,000 m (2,300–6,600 ft) elevation in the Taurus Mountains of southern Turkey.
Cyclamen parviflorum, the small-flowered cyclamen is a flowering perennial plant growing from a tuber, native to high elevations in the Pontic Mountains of northern Turkey. It is the smallest cyclamen species and the only one native to alpine tundra.
Cyclamen rohlfsianum is a species of perennial plant in the family Primulaceae. It is endemic to Libya. It grows from a tuber in shrubland, especially in limestone cracks, up to 450 m (1,500 ft) above sea level. It is one of the tenderest cyclamen species. The plant was discovered by Friedrich Gerhard Rohlfs in 1879, and was named after him in 1897 by Paul Friedrich August Ascherson.
Cyclamen alpinum is a perennial plant growing from a tuber, native to an area of southwestern Turkey, northwest of Antalya. It is isolated from other species of the Cyclamen coum group.
Cyclamen repandum, the spring sowbread, is a species of flowering plant in the family Primulaceae, native to southern Europe and some Mediterranean islands. It is the most widespread of a group of cyclamens with wide, heart-shaped leaves, often coarsely toothed or lobed, and late spring-blooming flowers with long, slender petals.
Cyclamen pseudibericum, the false Iberian cyclamen, is a species of flowering plant in the genus Cyclamen of the family Primulaceae, native to the Amanus or Nur and Anti-Taurus Mountains in southern Turkey. It is an herbaceous, tuberous perennial growing to 12 cm (5 in). It is similar to Cyclamen coum, but with longer petals.
Cyclamen mirabile, sowbread, is a species of flowering plant in the primrose family Primulaceae. A tufted, tuberous herbaceous perennial growing to 10 cm (3.9 in), it is native to Turkish pine woodland and maquis in southwestern Turkey. It belongs to the Cyclamen cilicium group of the genus Cyclamen. The species was identified and named in 1906.
Cyclamen rhodium is a species of flowering plant in genus Cyclamen of the family Primulaceae, native to the Peloponnese, Rhodes, and southwestern Kos. It is a tuberous perennial growing to 10 cm (4 in), with mottled, heart-shaped leaves and pink flowers, darker carmine pink at the base, appearing in spring. Like all cyclamens, the flowers consist of five upswept, reflexed petals.
Cyclamen creticum, commonly known as Cretan sowbread, is a small perennial herb endemic to Crete and Karpathos. It is closely related to Cyclamen repandum, and both are placed in subgenus Psilanthum. Some authorities consider C. creticum to be a subspecies of C. repandum.
