Sempervivum altum is a species of flowering plant in the family Crassulaceae, native to the Caucasus Mountains.
 Like other members of the houseleek genus, it grows succulent leaves in rosettes.
 The rosettes of "S. altum" are 1-5 cm across, and the leaves are pubescent or pilose.
 The flowers are pink edged with white, with yellow anthers, growing on a stem 30-40 cm tall.
 The species was described in 1936 by William Bertram Turrill based on specimens collected by P.L. Giuseppi in a 1935 expedition to the Caucasus Mountains.
 It is closely related to "S. ingwersenii" and "S. ossetiense" from the same region.
 s of June 2013 , the name is not accepted by the World Checklist of Selected Plant Families.
The flowering plant genus Ipheion (starflower, spring starflower) belongs to Allioideae subfamily of the Amaryllidaceae family.
 The World Checklist of Selected Plant Families no longer recognize the genus, regarding it as a synonym of "Tristagma", although The Plant List accepts two species.
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.
 The scientific name "Helleborus" derives from the Greek name for "H. orientalis", ἑλλέβορος "helléboros", from "elein" "to injure" and βορά "borá" "food".
 Many species are poisonous.
 Despite names such as "winter rose", "Christmas rose" and "Lenten rose", hellebores are not closely related to the rose family (Rosaceae).
Helleborus niger, commonly called Christmas rose or black hellebore, is an evergreen perennial flowering plant in the buttercup family, Ranunculaceae.
 It is poisonous.
Helleborus argutifolius (holly-leaved hellebore, Corsican hellebore) syn.
 "H. corsicus", "H. lividus" subsp.
 "corsicus" is a species of flowering plant in the family Ranunculaceae, native to Corsica and Sardinia.
 It is an evergreen perennial growing to 120 cm tall by 90 cm wide, with large leathery leaves comprising three spiny-toothed leaflets, and green bowl-shaped flowers in late winter and early spring.
Helleborus viridis, commonly called green hellebore, is a perennial flowering plant in the buttercup family, Ranunculaceae, native to Central and Western Europe, including England.
 All parts of the plant are poisonous.
Aethionema syn.
 "Eunomia" is a genus of flowering plants, within the family Brassicaceae, subfamily Brassicoideae.
 The genus is collectively known as the stonecresses.
 They originate from sunny limestone mountainsides in Europe and West Asia, especially Turkey.
Veratrum fimbriatum is an uncommon species of false hellebore, a type of plant closely related to the lily.
 Its common names are fringed false hellebore and fringed corn lily.
 It is endemic to California where it is a rare resident of the northern coastal scrub plant communities of Mendocino and Sonoma Counties.
 This flowering plant is a stout, hollow-stemmed perennial growing from a thick rhizome.
 The erect flowering plant bears several large, flat, green leaves near the base of the green stem.
 The large panicle inflorescence is packed with many distinctive, lacy-fringed flowers each up to a centimeter wide.
 The flower bud is club-shaped before it opens into a bloom of six frilly tepals, each of which bears two bright green or gold glands.
 The ovary and sepals extend straight outward as one thick stalk.
 The fruit is an oval-shaped capsule just under a centimeter long containing the seeds.
Helleborus foetidus, known variously as stinking hellebore , dungwort, setterwort and bear's foot, is a species of flowering plant in the buttercup family Ranunculaceae, native to the mountainous regions of Central and Southern Europe, Greece and Asia Minor.
 It is found wild in many parts of England, especially on limestone soil.
Adonis vernalis, known variously as pheasant's eye, spring pheasant's eye, yellow pheasant's eye and false hellebore, is a perennial flowering plant in the buttercup family Ranunculaceae It is found in dry meadows and steppes in Eurasia.
 Isolated populations are found from Spain in the west across Central Europe with fine examples in Valais, Switzerland, and southern Europe, reaching southern Sweden in the north and Abruzzo in the south, with its main area of distribution being the Pannonian Basin and the West Siberian Plain.
 In contrast to most other European "Adonis" species, the flowers appear in springtime, and are up to 80 mm in diameter, with up to 20 bright yellow petals.
