The common name of some species is globeflower[1] or globe flower. Native to the cool temperate regions of the Northern Hemisphere, with the greatest diversity of species in Asia, trollius usually grow in heavy, wet clay soils.[2] DescriptionThey are mostly herbaceous perennials, produce numerous fibrous roots, with bright yellow flowers, though some have orange to lilac coloured flowers. The name "globe flower" refers to the petals of T. europaeus and T. × cultorum which are curved over the top of the flower, forming a globe. But T. pumilus has flatter flowers, and T. chinensis has open flowers with prominent stamens.[3] EcologyAll trollius species are poisonous to cattle and other livestock when fresh, but their acrid taste means they are usually left uneaten. They are, however, used as food plants by the larvae of some Lepidoptera species including Silver-ground Carpet. CultivationSome species are popular ornamental flowers in horticulture, with several cultivars selected for large and brightly coloured flowers. The hybrid T. × cultorum[4] in particular is a source of several garden cultivars, including 'Superbus', which has gained the Royal Horticultural Society's Award of Garden Merit.[5][6] Image galleryReferences1. ^{{PLANTS|id=TROLL|taxon=Trollius|accessdate=12 December 2015}} {{Commons|Trollius}}{{Taxonbar|from=Q161588}}{{Ranunculales-stub}}2. ^{{cite web |url=http://novataxa.blogspot.com/2019/01/trollius-austrosibiricus.html|title=A New Species from South Siberia|publisher=Novataxa |accessdate=11 February 2019}} 3. ^{{cite book|title=RHS A-Z encyclopedia of garden plants|year=2008|publisher=Dorling Kindersley|location=United Kingdom|isbn=1405332964|pages=1136}} 4. ^{{cite web|title=Missouri Botanical Garden|url=http://www.missouribotanicalgarden.org/gardens-gardening/your-garden/plant-finder/plant-details/kc/b716/trollius-x-cultorum.aspx|accessdate=27 April 2013}} 5. ^{{cite web|title=RHS Plant Selector - Trollius × cultorum 'Superbus'|url=http://apps.rhs.org.uk/plantselector/plant?plantid=1952|accessdate=7 June 2013}} 6. ^{{cite web | url = https://www.rhs.org.uk/plants/pdfs/agm-lists/agm-ornamentals.pdf | title = AGM Plants - Ornamental | date = July 2017 | page = 103 | publisher = Royal Horticultural Society | accessdate = 25 December 2018}} 2 : Ranunculaceae genera|Trollius |
