Tropaeolum, commonly known as nasturtium, is a genus of roughly 80 species of annual and perennial herbaceous flowering plants. It was named by Carl Linnaeus in his book Species Plantarum, and is the only genus in the family Tropaeolaceae. The nasturtiums received their common name because they produce an oil similar to that of watercress.
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.
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, southern Turkey and neighboring islands and is prized for its variable leaf forms, which include some of the most striking of any cyclamen.

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 elegans is a perennial growing from a tuber, native to the Alborz Mountains in northern Iran and southeastern Azerbaijan. It is native to forest in the Alborz Mountains of northwestern Iran and extreme southeastern Azerbaijan below 500 m (1,600 ft) elevation, where it can even be found growing in moss on the lower limbs of trees.
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.

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.
