some sand added ; and they are increased by cuttings planted 

 ill sandy soil, and placed in a close warm situation, such as a 

 hotbed or a propagating pit. The flowers are for the most 

 part deliciously fragrant. There are many sorts known in 

 gardens, but the half of them require stove heat. The best 

 are J. affine, white ; J. revolutum, yellow ; and J. nudljiorum, 

 yellow and hardy. There are some pretty stove and green- 

 house varieties. 



JEFFERSONIA. [Berberidace^.] A neat hardy herba- 

 ceous perennial. Soil, sandy loam. Increased by division 

 of the plant, which should be done in spring, or by seeds. 

 J. diphylla, hardy perennial, flowers white, in May. 



JONQUIL. See Narcissus. 



JUDAS TREE. See Cercis. 



JUGLANS. Walnut. [Juglandaceae.] Hardy deciduous 

 trees, some of which are useful for their fruit, and others 

 ornamental on account of their habit and fine pinnated 

 foliage. Deep loamy soil. Increased by seeds, or by budding 

 or grafting. 



JUNIPERUS. Juniper. [Pinaceae.] Evergreens, many 

 of which are remarkably ornamental in habit, forming light, 

 spreading, more or less pendulous bushes or low trees. The 

 Junipers prefer a light loamy soil, but are not difficult of 

 culture in any that is moderately good, and not wet or heavy. 

 Increased with most facility by seeds, but the rarer kinds may 

 be propagated by grafting, or by cuttings of the firm young 

 shoots, planted in sandy soil on a shady border, and covered 

 by a hand-light. 



JURINEA. [Compositae.] Hardy herbaceous perennials. 

 Common soil. Division of the root. J. spectahilis, flowers 

 purple, in June. 



JUSTICIA. [Acanthaceae.] Stove sub-shrubby plants 

 of easy management. Soil, rich loam and leaf-mould. In- 

 creased by cuttings in sand in a hotbed ; and, being fast 

 growers, it is best to raise young plants annually. The species 

 of Justicia are now distributed among numerous new genera, 

 but for convenience we shall retain them under their old 

 names, selecting a few of the most desirable. J. carnea, 

 evergreen, flowers pink. J. nasuta, flowers white. J. nodosa, 

 pink. J. oblongata, rose pink. .J. speciosa, flowers purple.
