It started out as a green with a hint of purple in the middle as shown in these pictures. It's been only in deep shade shade, and now that spring is here, the new leaves are a dark purple. Here is a link to the pictures in case the uploads don't show up when it was still newly planted and had been in only partial shade. http://home-and-garden.webshots.com/photo/2944009950101627988CRLpaZ http://home-and-garden.webshots.com/photo/2245431530101627988JNBMes
Ditto to Heuchera. Now a very popular plant in UK with many new named cultivars being introduced. See this site for just a few! http://www.heucheraholics.co.uk/heuchera_shop.html
