THE FLOWER GROWER'S GUIDE. 



jacobinia or sericograpeis. — J. Ghiesbreghtiana, Mexico, is an acceptable 

 winter-flowering cool stove plant of easy culture. It forms plain bright green leaves, 

 and produces terminal panicles of scarlet flowers. Propagation is effected by inserting 

 cuttings of young shoots from March to July, in small pots of sandy soil plunged in a 

 close frame and a temperature of about 75°. Top the young plants at least twice to 

 make them branch, and gradually shift into larger pots. They may be flowered in 

 6-inch to 8-inch pots, and succeed in a mixture of equal parts loam, peat, leaf-soil and 

 sand. During the summer the plants may be arranged in sunny pits or frames, and 

 should be returned to a light position and temperature of 55° to 65° to flower. When 

 well established in their flowering pots, abundance of water varied by liquid manure 

 should be given. After flowering, give rather less water for a fortnight, then cut down 

 the growths to near where they last branched. When fresh shoots are beginning to 

 form, shake the roots nearly free of soil, and after trimming them with a knife, re-pot in 

 sizes just large enough to hold them. Give a shift when this is needed, and in other 

 respects treat as advised in the case of young plants. 



jasminum. — A few tropical species are cultivated in plant stoves, but are by no 

 means commonly grown. Two or three flowers seem capable of perfuming a house, 

 but, unfortunately, they fall quickly after they are cut. J. gracillimum, Northern 

 Borneo, is a small-growing species, forming a neat bush, and produces panicles of white 

 sweet-scented flowers in the winter. J. Sambac, India, white fragrant flowers, is more 

 twining in habit ; this and the double forms, Duchesse d'Orleans and flore pleno, succeed- 

 ing best when trained against pillars, where they produce a few or many flowers nearly 

 all the year round. Propagation is effected from March to September by cuttings of 

 firm shoots inserted in sandy peat, and closely covered with glass, in a temperature of 

 65° to 75°. Pot in a mixture of equal parts of sandy loam and peat. J. gracillimum 

 (Fig. 159) succeeds well in a hanging basket, in which case the plants should be 

 freely topped to make them bushy. They thrive and flower in an ordinary stove 

 temperature, and should not be allowed to become dry at any time. Assist root- 

 bound plants with liquid manure. Prune away irregular growths in February, and 

 soon after re-pot the plants. 



justicia. — Justicias are frequently confused with Jacobinias and other kinds of 

 plants, but it is the popular term for the species to be described, and is retained accord- 

 ingly. J. aurea, also known as Cyrtanthera catalpge folia, Honduras, forms broad leaves, 

 and produces yellow flowers in July. J. carnea, Kio Janeiro, is of a sturdy habit of
