Cypella. Iridaceoe. 



Propagated by offsets (cormels) and by seed as soon as ripe. 

 Cyperus. Cyperacece. 



Propagated either by seed-heat, or by divisions. C. alternifolius, 

 the umbrella-plant, propagates readily from the crown or rosette of 

 leaves. Cut off the crown, with an inch or two of stem remaining, 

 and set on sand or moss. Cut in the leaves. New plants will 

 start from the axils. See Papyrus. 



Cyphomandra (Tree Tomato). Solanacece. 



Seeds are employed, started under glass and handled as are 

 eggplants ; also by cuttings of growing shoots under glass. 



Cypripedium of florists : Paphiopedilum and Phragmipedilum. 

 Cyrtomium. Polypodiacece. 



Spores; see Ferns, page 312. 

 Cytisus. Leguminosas. 



Grown from seeds and cuttings. Seeds are usually sown in 

 spring, under glass or in the open. If well grown and frequently 

 transplanted, seedlings should make blooming plants the second 

 season. 



Cuttings of firm young wood may be struck in early spring under 

 glass, making flowering plants the next spring. Layers are some- 

 times used. Forms of some of the species may be grafted on C. 

 nigricans or on laburnum (which see) ; greenhouse kinds may be 

 worked on the common C. canariense. 



Daedalacanthus. Acanthaceoe. 



Propagation is by cuttings as for justicia, which see. 

 Dahlia. Composites. 



Commonly grown from tubers, which are dug in the fall and 

 stored in the cellar, like potatoes. Each fork of the root may be 

 broken apart and planted separately in the field ; or the pieces 

 may be started early in pots or boxes. It is essential that each 

 piece have an eye or bud at the top ; to insure this, it is well to 

 start the roots in the house in spring before dividing them. 



Single varieties, and sometimes the doubles, are grown from 

 seeds. New varieties, or at least many variations, are produced 

 from seeds, particularly if cross-pollination has intervened. Good 

 blooming plants, particularly of the singles, may also be had for
