==Cultivation==
[[File:Tradescantia_greece.jpg|thumb|Tradescantia plants are widely used for ground cover in gardens|250px]]
Spiderworts are popular in Europe and North America as ornamental plants. Temperate species are grown as hardy garden perennials, while tropical species such as ''T. zebrina'' and ''T. spathacea'' are used as house plants.{{sfn|Hawke|2010}} Their popularity and easy spreading nature has led to some species being considered serious weeds in certain places (see [[#Weeds|below]]).

Most cold-hardy garden plants belong to the Andersoniana Group (often referred to with the [[Validly published name (botany)|invalid name]] ''Tradescantia'' × ''andersoniana'').{{sfn|Dave's Garden|2015|loc=[http://davesgarden.com/guides/articles/view/794/ Tod Boland. Spiderwort Hybrids - Tradescantia X andersoniana. September 1, 2012]}} This is a group of interspecific hybrids developed from ''[[Tradescantia virginiana]]'', ''[[Tradescantia ohiensis|T. ohiensis]]'', and ''[[Tradescantia subaspera|T. subaspera]]'', which have overlapping ranges within continental North America.{{sfn|Hawke|2010}} These plants are clump-forming herbaceous perennials, with individual cultivars mainly differing in flower colour.{{sfn|Christman|2005}} 

A wide range of tender tropical species are cultivated as houseplants or outdoor annuals in temperate locations, including ''Tradescantia zebrina'', ''T. fluminensis'', ''T. spathacea'', ''T. sillamontana'', and ''T. pallida''.<ref>{{cite web |last=Espiritu |first=Kevin |date=23 March 2017 |title=Wandering Jew Plant: Care, Types, and Growing Tips |url=https://www.epicgardening.com/wandering-jew-plant |access-date=2 November 2021 |publisher=Epic Gardening}}</ref><ref name="BHG">{{cite web |title=Tradescantia |url=https://www.bhg.com/gardening/plant-dictionary/houseplant/tradescantia |access-date=2 November 2021 |publisher=[[Better Homes and Gardens (magazine)|Better Homes & Gardens]]}}</ref> They are typically grown for their foliage, and many have colourful variegated patterns of silver, purple, green, pink, and gold.<ref name="BHG"/>

The [[International Society for Horticultural Science]] appointed Tradescantia Hub as an International Cultivar Registration Authority (ICRA) for ''Tradescantia'' in 2022. As an ICR authority, the Hub is responsible for recording and maintaining a checklist of the correct names for all cultivars in the genus.<ref>{{cite web |title=ICRA Report Sheet: Tradescantia Hub |url=https://www.ishs.org/sci/icralist/109.htm |publisher=International Society for Horticultural Science |access-date=17 October 2023}}</ref>
