Yucca 



(453 ) 



Zaiuzianskia 



Propagation. liy suckers from, or divisions of, 

 the old plants; also by means of cuttings of the 

 fleshy roots, inserted in rather sandy soil in a 

 close frame, with heat according to the character 

 of the species or variety. 



Soil. A light, rather rich soil suits the Yuccas 

 best. A good, sandy loam, with about one-fifth of 

 its bulk mortar rubbish, and another fifth old 

 Mushroom bed manure, is suitable. Heavy loam' 

 will need more of the mortar rubbish. 



Other Cultural Points. Drainage must in all 

 cases be free, or the plants will rot. Where they 

 are to be grown in the open ground it will be 

 well to dig the beds 3' and drain thoroughly. Pot 

 plants should be potted firmly. The outdoor 

 clumps benefit considerably by annual mulchings 

 of rotted ynrd dung ; pot plants may have liquid 

 manure in the summer. With regard to the quantity 

 of water needed, Yuccas come halfway between 

 the Cacti and ordinary plants. In winter one 

 watering will carry them on for weeks. Hardy 

 species that are grown in pots, and stood in orna- 

 mental vases, may require to be taken indoors 

 during long spells of frost, for the low temperature 

 lias a greater effect upon them when they are in 

 pots than it has upon plants in the open ground.

HYBRID YUCCAS. 



Recently several new hybrid Yuccas have been 

 introduced to commerce, and when more generally 

 cultivated will add much to the favour being now 

 shown to these effective plants. The following is 

 a list of those at present in commerce. AH are 

 white unless otherwise stated. 



a,lbella. hdy. 



elegantissima, hdy. (fila- 

 mentosa major X glori- 

 osa). 



elmeiisis, hdy. (fila- 

 mentosa major X 

 gloriosa). 



Guiglielmi, hdy., one of 

 the finest. 



Imperator, hdy., very 

 fine (fllamentosa major 

 X recurvifolia). 



liliacea, hily. (filamentosa 

 X rupestris). 



magnifica, hdy. (filamen- 

 tosa flaccidaXgloriosa).

 mentosa X gloriosa). 



prajcox, hdy., early 

 bloomer. 



Treleasii, hdy., early, 

 large spikes and flowers. 



viridiflora, hdy. , large 

 srikes of light green, 

 flowers. 



ZACINTHA. 



Verrucosa, the only species (ord. Compositas), 

 is a hardy annual, 6" to 12" high, with yellow 

 flowers in summer. It is of little garden value. 

 Increased by seeds in light, sandy loam. 



ZALACCA (*yn. SALACCA). 



Dwarf, almost stemless, Palms (ord. Palmac), 

 seldom grown. 



Principal Species : 



edulis, Ivs. erect, clustered, divisions 2' long, 2" 

 broad, wh. beneath, sharp prickles (fyns. blumeana 

 and wallichiana). 



ZALUZANIA (syn. FEUDINANDA, in part). 



Stove, half-hardy, and hardy shrubs (ord. Com- 

 positse). Propagation, by seeds and cuttings. 

 Soil, light loam. Ferdinanda eminens (correctly 

 Podachasnium paniculatum), stove, white, is the 

 only species in cultivation. 



ZALUZIANSKIA (syn. NYCTEIUSIA). 

 Greenhouse and half-hardy annual and peren- 

 nial herbs and sub-shrubs (ord. Scrophularinea;).
