WOOD SORREL. See Oxalis. 



WOODWARDIA. rPolyj30cliace8e.] Hardy and deciduous 

 ornamental ferns. Peat and loam. Division. The cliief aie 

 W. onocleoiJes, W. raJicans, and W. Vinjinica. 



WORM GRASS. See Spigelia. 



XERANTHEMUM. [Comj^ositae.] . Hardy annuals of 

 the composite kind, now almost expelled from gardens by tlie 

 gayer annuals from California and elsewhere. They must not 

 be confounded with the showy yellow and white everlasting 

 flov;eis, as they are called, which have been, and, indeed, now 

 are sometimes named Xerantliemum. They are among the 

 most easily cultivated of annuals, requiring only to be sown 

 about the end of March in the open border, and thinned out 

 for flowering. A succession may be sown a month later than 

 the first sowing if it is required. 



YEW. See Taxus. 



YUCCA. Adam's Needle. [Liliaceae.] Fine exotic- 

 looking shrubs, most of them hardy ; others require some 

 amount of protectioiL They are Aloe-like, with narrow leaves, 

 some growing up with an erect stem, which in time becomes 

 forked, and others being almost stemless, the leaves growing 

 close to the ground. The flosvering stem in all is erect, 

 bearing a close panicle of large cream-coloured drooping 

 Tulip-like blossoms. They all grow in loamy soil, and the 

 hardy kinds have a fine effect planted sparingly in prominent 

 positions on rockwork. The best are Y. draconis, Y. fda- 

 menlosa, Y. gloriosa, and Y. recurva. 



ZAMIA. [Cycadaceae.] A genus of remarkable-looking 

 plants, related both to palms and ferns, and exceedingly 

 interesting in a collection of plants. There are some few 

 greenhouse species. They require to be planted in light 

 sandy soil ; and, as they often exist for a long time with but 

 little progress, the pots should be carefully drained and as 

 carefully watered. 



ZAU'SCHNERIA. [Onagraceae.] Pretty half-hardy per- 

 ennial. It forms a densely-branched mass, bearing numerous 

 erect scarlet Fuchsia-like flowers, and is well suited for the 

 decoration of the flower garden during summer. It propa- 

 gates very freely from cuttings, or also by division. The old 

 plants require to be kept rather dry in winter. It may be
