Crocus chrysanthus 'Zenith' features large, violet-blue flowers with paler, near-white interiors that hold the golden stamens and orange pistils. Richly perfumed. Species, or snow crocus, are some of the first bulbs to emerge in the late winter, two weeks before other forms. They are great in the border, in containers, and in rock gardens. They can also be planted in your lawn, but try to hold off on mowing them as long as possible so they can build up energy for next year.
