Soldanella minima 'Alba'

Least Alpine Snowbell.  Perhaps the daintiest Soldanella, we have this from three different sources as Soldanella minima 'Alba', S. austriaca 'Alba' and S. carpatica 'Alba' and can see no difference between the three and are putting them under the umbrella of Soldanella minima 'Alba' based on the "minima" size of the leaves and plant. How's that for technical taxonomy? Allied to Primula and native to the eastern Alps where it grows in low turf, rock outcrops and crevices. This is the less-common white form and while smaller by half or more than the more familiar species, it is just as tough as the full-sized versions, despite being an ideal choice for the fairy garden.  Light shade to morning sun.
