About Hardy cyclamen

A flat tuber, marbled leaves and pink autumn flowers. Roots come from the top and sides, not the base. The tuber grows larger every year.

Depth and spacing

Typical range: 2-3 cm deep and 10-15 cm apart. A general rule is to plant at two to three times the height of the tuber; check the label for your variety. The drawing is to scale for 2.5 cm deep and 12.5 cm apart (the size of the organ is illustrative); try your own measurements.

Cyclamen is grown from seed; tubers are not divided. Seed ripens under coiled stalks in summer.

Lifting and storing
