They appear in succession from October until April, beginning with the Christmas Rose (H. niger), and ending with the handsome crimson kinds.
The old white Christmas Rose is well known and much admired, but the handsome kinds with colored flowers have, hitherto, not been much known.
The white-flowered group is the most important, as it contains the beautiful old Christmas Rose.
The common white Christmas Rose is a favorite pot-plant, and if required for potting its foliage should be protected from injury.
The divided plants, if placed in a bed of good light soil, and undisturbed, will be good flowering plants in a couple of years, but four years are required to bring a Christmas Rose to perfection.
