It is a delicate mat-forming evergreen perennial growing to {{convert|5|cm|0|abbr=on}} tall by {{convert|20|cm|0|abbr=on}} broad, with spikes of small, vivid deep blue flowers in spring, and leathery, oval leaves.[1] The white anthers of the flowers may possibly be the source of the name milkwort. The specific epithet calcarea means "growing in lime", though this plant will grow in a range of soils.[2] It prefers sharply drained conditions, and is suitable for cultivation in an alpine garden. The cultivar ‘Lillet‘ has gained the Royal Horticultural Society’s Award of Garden Merit.[3][4] References1. ^{{cite book|title=RHS A-Z encyclopedia of garden plants|year=2008|publisher=Dorling Kindersley|location=United Kingdom|isbn=1405332964|pages=1136}} {{Taxonbar|from=Q163756}}2. ^{{cite book|last=Harrison|first=Lorraine|title=RHS Latin for gardeners|year=2012|publisher=Mitchell Beazley|location=United Kingdom|isbn=9781845337315|pages=224}} 3. ^{{cite web | url = https://www.rhs.org.uk/Plants/45904/i-Polygala-calcarea-i-Lillet/Details | title = RHS Plantfinder - Polygala calcarea ‘Lillet’| accessdate = 7 May 2018}} 4. ^{{cite web | url = https://www.rhs.org.uk/plants/pdfs/agm-lists/agm-ornamentals.pdf | title = AGM Plants - Ornamental | date = July 2017 | page = 80 | publisher = Royal Horticultural Society | accessdate = 7 May 2018}} 2 : Polygala|Flora of Europe |
