I bought an addition to my longed for Viola collection today. It is the White Wood Violet, Viola Albiflora. This is a herbaceous perennial plant with the leaves and flowers emerging directly from the rhizomes and forming a basal rosette. A mature plant may be 6″ across and 4″ high with the flowers rising higher than the leaves. The leaves are heart shaped as on Freckles. The flowers of this form of Viola Sororia are white except for delicate violet lines radiating from the throat of the flower. There is no noticeable scent. They flower for about six weeks emerging from mid to late spring according to the weather. During the summer cleistogamous flowers without petals produce seeds, which are flung outward by mechanical ejection from the three-parted seed capsules. The root system consists of thick, horizontally branched rhizomes with a tendency to form vegetative colonies. As they are woodland plants they prefer dappled shade.
NB. Cleistogamy is a type of automatic self-pollination of certain plants that can propagate by using non-opening, self-pollinating flowers. Especially well known in peanuts, peas, and beans, this behaviour is most widespread in the grass family. However, the largest genus of cleistogamous plants is actually Viola.
