Cultivars
The d'Udine Parma violet features large, bluish-lavender flowers and a strong perfume.
The Neapolitan displays much paler flowers, although it very rarely blooms - it seems to be far more selective about its living conditions.
There is, also, a single variety of white parma: the Comte De Brazza. Hardy, and with a sweetly delicate perfume, the Comte produces pure white blooms, which in some climates, produce pale blue tips when they are exposed to plenty of good, strong spring sunlight.
The once much sought after Creme Yvette was a liqueur made of this particular strain of violets.
