I planted my first 3 Cyclamen hederifolium about 20 years ago. They love sandy soil so they're right at home here. They've naturalized in the lawn, in the gravel between the stones in the front walkway and under a bench by the front door. They also like it underneath my big rhododendrons.
Mostly they bloom before their wonderful ivy-like variegated foliage appears.
But sometimes the two come together.
Colchicum is often called a water lily fall crocus even though it's not really a crocus. They bloom in early October. Then in the spring their foliage which looks a lot like calla lily foliage comes up and lasts for a few months before it turns to mush.
The flowers are simply wonderful though they don't always hold up real well in our fall rains.
Both the other two fall crocuses I grow are true crocus and they both have lovely lavender flowers. The saffron crocus is sterile and multiplies only by creating more little bulbs. The Crocus kotschyanus self seeds and has been happily multiplying for years.
Saffron crocus is the source of that expensive spice, saffron. Each little saffron thread is the stigma of the flower and each flower only produces 3 threads. So it takes a lot of crocus to produce even an ounce of saffron.
