This well-known genus is among the earliest of our Spring flowers, often opening its flower-scapes the first week in January. It prefers a light, rich, loamy soil and a sheltered situation.
After they are done blooming and the leaves turn yellow, the bulbs should be taken up.
Propagate by dividing the bulbs when they are in a dormant state; keep them, in a cool dry place, covered with dry soil until the next planting season in October or the early part of November; plant them about three inches deep.
The Crocus may also be propagated by seeds sown about a quarter of an inch deep, as soon as ripe or in early Spring, in light rich soil, and left in the seed-bed for two years when the young conns may be separated and transplanted.
