Aqua crocus is a hardy 10 cm spring crocus supplied as 10 size 9/10 corms. Its cobalt-blue to blue-violet flowers, accented by orange stamens, open very early in sunshine.

Plant corms in fall, 5 cm deep and 5 cm apart, in loose, freely drained soil. Suitable for Zones 4 to 10, it thrives in rock gardens, borders, lawns, and open woodland. Let the narrow foliage yellow after flowering so it can replenish the corms. Where winter drainage is reliable and the soil never remains waterlogged, it returns and gradually develops into a natural-looking colony that becomes more generous over time.
