The effect of these purple crocus in the winter garden is remarkable. Their smooth, goblet-shaped heads look so delicate yet they are the toughest of little flowers. They naturalize in pretty clumps that look lovely against a frosty background, dabbing the whole winter scene with purple. You can buy ten, twenty, thirty or fifty bulbs with this order. To plant them, dig a hole about 6 cm, put in the bulbs, cover with soil and then water. Nature will do the rest.
