planted out in any moderately good garden soil, and requires 

 no subsequent culture beyond what is routine. Z. Callfornica 

 is the only one cultivated. 



ZEA. Maize. [Gramineae] Stately gi'assy plants, 

 useful for effect. Common soil. Seeds reared in a gentle 

 heat, and planted out in May. 



ZENOBIA. [Ericaceae.] Fine hardy shrubs, allied to 

 Andromeda, and requiring the same treatment. Peat soil. 

 Layers. 



ZEPHYRANTHES. [Araaryllidacefe.] Pretty dwarf 

 bulbs, nearly related to Amaryllis and Habranthus, and 

 requiring the same mode of culture. One or two kinds are 

 hardy. 



ZICHYA. [Leguminosae, § Papilionacese.] Handsome 

 greenhouse evergreen climbing shrubs, formerly named Ken- 

 nechja, and requiring the same culture as that genus. The 

 best are Z. coccinea, flowers scarlet ; Z. pannosa, flowers 

 crimson ; Z. tricolor, flowers red, yellow, and purple ; 

 Z. villosa, flowers vermilion. 



ZINNIA. [Compositse.] A genus of Mexican annuals, 

 bearing flower-seeds of many different colours, seedling varie- 

 ties having become numerous. The most ornamental species 

 is Z. elegans. winch grows best in peaty soil and in a cool 

 situation. The plant may be termed coarse, and is better 

 looking in moderate than in rich soil. The seed may be sown 

 in the open ground, or in heat, according to the time it is 

 desired to be in flower. When large enough it may be planted 

 out at once into beds a foot apart, or in the border three in a 

 patch. When seed has been saved from a single plant, and 

 none other has been near, the plants have come pretty con- 

 stant to the parent ; but, generally speaking, in the seed that 

 is purchased we obtain all the colours from scarlet to light 

 pink and to dark crimson, and all the shades from dark 

 chocolate to light purple and lilac. It is a difficult matter to 

 produce, year after year, anything like constancy in annuals ; 

 for the only way is to destroy all others that can cross the 

 seed, or to isolate those for seeding so that nothing can reach 

 them. Muslin bags have been tried with some effect, but it 

 must be done very early.
