About this plant
The species comes in a range of colours, generally in lavender tones but may be white. The outside of the petals often carries spots and streaks. The plants have orange or yellow throats with yellow and orange stamens. The flowers are fragrant. The naturally variability has given rise to a number of distinctive cultivars. The slender leaves arise with the flowers. These crocus are frequently grown in the garden and are generally hardy though can be killed in very cold winters. It can flower as early as January, though February is more likely.
