cyclamen

 

  • In cultivation cyclamen, especially species other than Cyclamen persicum, are selected as often for striking or unusual leaf patterns as for their flowers.

  • Description Cyclamen have a tuber, from which the leaves, flowers and roots grow.

  • Cyclamen hederifolium and Cyclamen repandum usually have leaves shaped like ivy, with angles and lobes, Cyclamen coum has nearly round leaves and Cyclamen persicum has heart-shaped
    leaves with a pointed tip.

  • In some older specimens of Cyclamen purpurascens and Cyclamen rohlfsianum growing points on the tuber become separated by shoulders of tissue and the tuber becomes misshapen.

  • In Cyclamen hederifolium older tubers commonly reach 24 cm (9+1⁄2 in) across, but in Cyclamen parviflorum tubers do not grow larger than 2 cm (3⁄4 in) across.

  • The storage organ of the cyclamen has no papery covering and, depending on the species, roots may grow out of any part.

  • Cyclamen repandum has petals much longer than wide, Cyclamen coum has stubby, almost round petals, and Cyclamen hederifolium usually has petals with proportions between the
    two.

  • [11] The shape of the tuber may be near spherical, as in Cyclamen coum, or flattened, as in Cyclamen hederifolium.

  • Gallery[edit] Cyclamen bloom in different seasons, depending on the species.

  • The dark color on the flower nose varies in shape: Cyclamen persicum has a smooth band, Cyclamen hederifolium has a streaky V and Cyclamen coum has an M-shaped splotch with
    two white or pink ‘eyes’ beneath.

  • Cyclamen purpurascens and Cyclamen colchicum, however, originate from cooler regions in mountains and their leaves remain through the summer and wither only after the next
    year’s leaves have developed.

  • [17] Species[edit] As of May 2021, Plants of the World Online accepted the following species: Cyclamen africanum Boiss.

  • Cultivation and uses See also: List of cyclamen diseases Cyclamen are commonly grown for their flowers, both outdoors and indoors in pots.

  • The leaf margin may be smooth, as in Cyclamen coum subsp.

  • Most species have leaves variegated in several shades of green and silver, either in an irregular pattern of blotches or an arrowhead or Christmas-tree shape.

  • [12] Leaves[edit] Christmas tree pattern on leaf Lower side of a leaf Cyclamen coum Leaves sprout from growing points or floral trunks on top of the tuber.

  • Cyclamen persicum and Cyclamen coum root from the bottom; Cyclamen hederifolium roots from the top and sides.

  • Many species have a pink form and a white form but a few have only one color, such as Cyclamen balearicum, which is always white.

  • Tuber[edit] Tuber and roots in genus cyclamen A tuber of Cyclamen purpurascens with three floral trunks The storage organ of the cyclamen is a round tuber, which develops
    from the hypocotyl (the stem of a seedling).

  • The stems of Cyclamen hederifolium and Cyclamen coum coil starting at the end, Cyclamen persicum arches downwards but does not curl, Cyclamen rohlfsianum coils start near
    the tuber and Cyclamen graecum coils in both directions, starting in the middle.

  • Petal shape varies depending on species and sometimes within the same species.

  • The shape of the leaves varies among the species and even among different specimens of the same species.

  • The tuber may produce roots from the top, sides or bottom, depending on the species.

  • Selected cyclamen cultivars have white, bright pink, red or purple flowers.

  • Hardiness[edit] Cyclamen species range from frost-hardy to frost-tender.
