Many or even most species provide year - round splashes of colouration – red , wine , violet , orange , lime , copper , silver gray , gold … and that’sjust the foliation !
On top of this , many varieties ’ leaves change colour from one season to another , often dramatically .
diversification ? But of path . And there ’s a incentive : most varieties bear thyrsus of tiny peak in summertime ; sometimes their colour matches that of the foliage and sometimes they provide an emphasis or full complement .
And that , in a nutshell , is Heuchera .
It is hardly any curiosity that these eye - pulling plants have blow up in popularity over the retiring 20 old age , with a concomitant detonation in the phone number of variety .
While Heuchera has more than 50 species ( not including synonyms ) , hybrids and cultivars figure several hundred and counting.1Heuchera ( Alumroot , Coral Bells , Heuchera ) . ( n.d . ) . North Carolina Extension Gardener Plant Toolbox . Retrieved March 17 , 2023 , fromhttps://plants.ces.ncsu.edu/plants/heuchera/

Habitat & Growing Conditions
Genus Heuchera let in many potent and tough mintage that grow in many locales and conditions that are inhospitable for most industrial plant life , such as rocky fissures , barren slopes , and canyon floors .
Other specie maturate in more hospitable locations , such as wooded hillsides and grasslands .
Furthermore , as they originate through almost the comprehensiveness of North America and throughout its duration from Northern Canada to Southern Mexico , different species are acclimate to very dissimilar temperature , humidity , and rainfall conditions .
As a result , different smorgasbord have different preference and tolerances depending on which coinage they were hybridise or cultivated from .
In cosmopolitan , H. villosacultivars are hardier at both temperature extremes thanH. micranthacultivars .
That allege , as British weather does not get very hot – at least not the way it does in , say , the South of Spain – the chances that a Heuchera mintage or variety will be pretend by high temperature are slender .
Most mixture are H6 hardy – making them suitable for almost all out-of-door arena of the UK .
How To Grow Heuchera
