It has gained the Royal Horticultural Society's Award of Garden Merit.[5][6] There are many cultivars with a variety of flower colors, including white, red, pink, and dark purple.[7] References1. ^{{cite web|title=International Plant Names Index|url=http://www.ipni.org/ipni/idPlantNameSearch.do?id=145511-1&back_page=%2Fipni%2FeditSimplePlantNameSearch.do%3Ffind_wholeName%3DTrachelium%2Bcaeruleum%2B%26output_format%3Dnormal|accessdate=23 April 2013}} {{Taxonbar|from=Q882775}}2. ^1 {{GRIN | accessdate = 23 January 2018}} 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 book|last=Harrison|first=L.|title=RHS Latin for Gardeners|year=2012|publisher=Mitchell Beazley|location=United Kingdom|isbn=9781845337315|pages=224}} 5. ^{{cite web|title=RHS Plant Selector - Trachelium caeruleum|url=http://apps.rhs.org.uk/plantselector/plant?plantid=4206|accessdate=5 July 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 = 102 | publisher = Royal Horticultural Society | accessdate = 23 December 2018}} 7. ^Liang, R. and B.
