TROP^OLUM. 



These are handsome plants ; most of the 

 greenhouse kinds are of t^vining hahit and 

 may be grown as climbers, planted out or 

 in pots, or thev can be kept in pots and 

 trained to supports in the form of a bush, 

 or otherwise, at the discretion of the culti- 

 vator. 



Thev may be increased from seeds sown 

 in an intermediate heat in shallow pans, 

 in a mixture of sifted peat and sand ; the 

 seed can be put in at any time of the year, 

 but we prefer the latter end of summer as 

 soon as they are ripe ; cover them slightly 

 and keep the soil moderately moist. When 

 the little plants are up stand them close to 

 the glass, using a little shade so long as the 

 sun is powerful, with air daily, and enough 

 water to keep the roots in a healthy con- 

 dition. Through the winter let them be 

 in a temperature of about 45° or 50° ; in 

 the spring move singly into small pots, 

 varjing the size in proportion to the 

 strength of the kinds grown ; use soil 

 similar to that in which the seed was sown, 

 but with less sand in it. Keep now, and 

 through the summer, in a warm green- 

 house temperature, with air and a little 

 shade in sunny weather, supporting the 

 shoots with sticks so far as needful, and 

 keeping the soil moderately moist. Give 

 larger pots to such as seem to require them 

 further on in the summer. Admit more 

 air in autumn, and keep through the fol- 

 lowing -winter at about 45°. They will 

 need more pot-room in spring, and in other 

 matters should be treated as in the season 

 before. The plants should bloom this 

 summer, after which keep drier at the 

 roots, especially in the case of the herbaceous 

 sorts, while at rest. All that is required 

 in subsequent years is to give larger pots 

 to those that are grown in this way ; the 

 stronger-growing kinds can, if preferred, 

 be planted out. 



The following are all handsome flowered 

 sorts : — 



T. azureum. A Chilian species, with 

 blue flowers, produced in autumn. 



T. brachyceras. Flowers yellow ; a sum- 

 mer bloomer. From Chili. 



T. Jarrattii. Red and yellow ; blooms 

 in summer. From Santiago. 



T. pentaphyllum. Flowers orange and 

 yellow, produced in summer. A native of 

 Monte Video. 



T. polyphyllum. Orange and yeUow ; 

 a summer flowerer. Chili. 



T. speciosum. Has scarlet flowers, forth- 

 coming in summer. From South America. 



T. tricolorum. A slender-growing, beauti- 

 ful kind that bears a profusion of orange 

 and purple flowers in spring or summer. 

 It comes from Valparaiso. 



Insects. — Aphides and red spider ^viU 

 live on most of the kinds of Tropaeolum ; a 

 free use of the syringe is the best mode of 

 dealing with the spider ; for aphides fumi- 

 gate. 



TUPIDANTHUS CALYPTRATUS. 



This species often appears under the 

 name of Aralia calyptratus, with which it 

 is synonymous. In the early stages of its 

 growth the plant has a somewhat bushy 

 form, but as it gets older it assumes a 

 climbing habit. For decorative purposes 

 it is most useful while in a young state. 



It can be increased by cuttings and 

 grown on in the same way as advised for 

 Aralia Sieboldii, which see. It does weU 

 in a greenhouse, and comes from the Khasya 

 Mountains. 



TYD.ffiA. 



A genus of herbaceous stove Gesnerads,. 

 in appearance and general character much 

 like Achinienes. Among the kinds in 

 cultivation several are species, but more 

 are hybrids. Although they may be had 

 in flower at almost any time of the year^ 

 they are most useful in the autumn and 

 ^vinter. 



Their cultivation in most respects is like 

 that advised for Achimenes, which see,, 

 except that they must not be dried oft' as 

 Achimenes require to be. 



T. Ailsa. Vermilion, yellow and crim- 

 son. 



T. Amazon. Vermilion, red, yellow^ 

 and crimson. 



T. Bomb. Crimson and yellow. 



T. Cecilia. Red, yellow, and crimson. 



T. Chamaliere. Red and yellow. 



T. Elaiiie. Purple-rose, yellow, and 

 crimson. 



T. gigantea. Vermilion, and bright 

 yellow. 



E. Hypata. Rose, white, and crimson.
