'''''Trollius''''' is a [[genus]] of about 30 [[species]] of [[plant]]s in the [[Ranunculaceae]], closely related to ''[[Ranunculus]]''. The common name is '''globeflower''' or '''globe flower'''. They are native to the cool temperate regions of the [[Northern Hemisphere]], with the greatest diversity of species in [[Asia]], and usually grow in heavy, wet [[clay]] soils. They are mostly [[herbaceous]] [[perennial plant|perennial]]s with bright yellow [[flower]]s, though some have orange to lilac coloured flowers. The name "globe flower" refers to the petals of ''[[Trollius europaeus|T. europaeus]]'' which are curved over the top of the flower to appear like a spherical [[globe]]; however, many of the other species have more open, flatter flowers. All ''Trollius'' species are [[poison]]ous when fresh to [[cattle]] and other [[livestock]], but their acrid taste means they are usually left uneaten. They are, however, used as food plants by the [[larva]]e of some [[Lepidoptera]] species including [[Silver-ground Carpet]]. Some species are popular ornamental flowers in [[horticulture]], with several [[cultivar]]s selected for large and brightly coloured flowers. {{Inc| Trollius (old German, trol, something round; trollblume, in allusion to the shape of the flowers). Ranunculaceae. Globe-flower. A group of neat hardy herbaceous perennials of a dozen or more species, mostly found in moist or marshy places of the North Temperate zone; useful in garden borders. Roots fibrous, thickened: lvs. palmately divided or lobed: fls. large, solitary, whitish, yellow, golden yellow, or purplish, those in cult. usually yellow- or orange-fld.; petals 5 to many, small, unguiculate, with a nectariferous pit at the base of the blade; sepals 5-15, large, usually constituting the showy part of the fl.; stamens many; carpels 5 to many, sessile, many-ovuled: follicles in a head.—Very like Ranunculus in general appearance, but distinguished at once by bearing follicles rather than achenes. Trolliuses are grown for the beauty of their globular flowers and show of dark green leaves. They are suited to wet sunken gardens, wild borders, and edges of water-gardens, although in a good garden soil not lacking in moisture they do well. They may be increased either by seeds or by dividing the old plants; but the young plants grow slowly at first, and will not flower before the second season from seed. The usual globe-flower of the horticulturist is T. europaeus, with incurving sepals so that the flower has a ball-like appearance; in most of the species the sepals spread nearly or quite horizontally. They bloom in spring and early summer. T. aurantiacus, Hort., described as lemon-yellow: probably a form of T. europaeus.—T. Excelsior, Hort., and T. hybridus, Hort., with deep orange fls., are probably T. europaeus forms. {{SCH}} }} ==Cultivation== {{edit-cult}}<!--- Type cultivation info below this line, then delete this entire line --> ===Propagation=== {{edit-prop}}<!--- Type propagation info below this line, then delete this entire line --> ===Pests and diseases=== {{edit-pests}}<!--- Type pest/disease info below this line, then delete this entire line --> ==Species== About 30, including:<br/> ''[[Trollius acaulis]]''<br/> ''[[Trollius altaicus]]''<br/> ''[[Trollius asiaticus]]''<br/> ''[[Trollius chinensis]]''<br/> ''[[Trollius dschungaricus]]''<br/> ''[[Trollius europaeus]]''<br/> ''[[Trollius farreri]]''<br/> ''[[Trollius japonicus]]''<br/> ''[[Trollius laxus]]''<br/> ''[[Trollius ledebourii]]''<br/> ''[[Trollius lilacinus]]''<br/> ''[[Trollius paluster]]'' <br/> ''[[Trollius papaverus]]''<br/> ''[[Trollius pumilus]]''<br/> ''[[Trollius ranunculinus]]''<br/> ''[[Trollius yunnanensis]]'' Hybrids: *''[[Trollius x cultorum]]'' ==Gallery== <gallery> Image:Globeflower Trollius laxus Flower 2400px.jpg|''Trollius laxus'' Image:Iceland_Plants_4898.JPG|Trollius sp.
