Filling an alpine trough with colour is Primula marginata, a native to the Alps. The rosette of evergreen foliage is toothed around the edges and white farina is found on both the upper and underside of the leaves. Older plants gain a woody appearance as the stem elongates with each growing season, shedding the lower leaves.
A variable species in flower, having a colour range from dark purple through to white, resulting in many named cultivars within the horticultural trade.
On a warm day a faint, most unusual scent, a mix of wood smoke and aged tobacco can be discerned emanating from the flowers. Several flowers are held on a flimsy peduncle.
