TUB 



The first has an herbaceous, trailing stem : 

 the leaves almost circular, smooth, grayish : the 

 flowers axillary, oa very long peduncles ; com- 

 posed of five acute-pointed petals, the two up- 

 per large and rounded, the three under narro>.v, 

 jointed together at bottom, and lengthened out 

 into a tail two inches long. 



Thire are varieties with deep orange-coloured 

 flowers inclined to red, with pale yellow flowers, 

 and with double flowers. 



The second species is larger in all its parts : 

 the borders of the leaves are indented almost 

 into lobes ; and the petals are rounded at the 

 top. The fruit consists of three berries, be- 

 coming juiceless when ripe, fungous, deeply 

 grooved and wrinkled, gibbous on one side, an- 

 gular on the other, narrowing upwards. It be- 

 gins to flower ill July, and continues till the ap- 

 proach of winter. 



There are varieties with pale yellow flowers, 

 orana;e coloured flow'ers,andthedoubie-flowered. 



Thevare both natives of Peru, and commonly 

 esteemed to be annual plants, though they may 

 be continued through the winter, if they are 

 kept in pots, and sheltered in a green-house or 

 glass case, in like manner as the variety with 

 double tlowers. 



The stalks will climb six or eight feet high, 

 when thev are trained up, and thus the flowers 

 make a good appearance ; but when they trail 

 upon the ground, they will spread over the 

 neighbouring plants and become unsightly : the 

 flowers are frequently eaten in salads; they 

 have a warm taste like the garden cress, and 

 hence the plant has its common name of Nas- 

 turtium j they are likewise used for garnishing 

 dishes : the seeds are pickled, and by some are 

 preferred to most pickles for sauce, under the 

 false name of capers. 



Culture. — These plants in all the single varie- 

 ties may be increased by seeds, whicli should be 

 sown in the spring in patches where they are to 

 flower in the borders, or in drills in the garden. 



They afterwards only require to be kept free 

 from weeds, and to be well supported by sticks. 



The double variety must be increased by plant- 

 ing cuttings of the branches in pots of light 

 mould in tlie early part of summer, placing them 

 in the shade, and giving frequent light water- 

 ings : those planted early may be rendered more 

 forward by being plunged in a moderate hot-bed. 



It requires to be protected in the green-house 

 in the winter, being well supported with sticks. 



They all afford variety in the borders, clumps, 

 &c. in the summer, and the double sorts among 

 potted plants. 



TROWEL, GARDEN, a trowel made of 

 iron, in a hollow or scooped form, which is an 



useful implement in taking up numerous sorts 

 of small plants and bulbous roots, and replant- 

 ing them in jiots, sowing in patches, and various 

 other similar light works : it should be from 

 six to twelve inches long in the plate, and half 

 as broad, and fixed on a short handle, to hold 

 with one hand. From its being hollowed semi- 

 clrciilarly, it is remarkably handy in removing 

 many sorts of small plants with a ball or lump 

 of earth whole about their roots, so as not to 

 feel their removal ; lifting several sorts of bul- 

 bous flower roots, after the flowering is past in 

 summer; planting bulbs in patches or little 

 clumps about the borders, and also for digging 

 small patches in the borders for sowing hardy 

 annual flower-seeds on; likewise for filling mould 

 into small pots in planting any sort of plants, 

 stirring the surface of the mould in pols, and 

 fresh earthing them when necessary : it is also 

 highly useful for filling in earth about plants in 

 hot-beds, and under frames, or any small com- 

 partments where a spade cannot be readily in- 

 troduced. 



They should be had of diflferent sizes to suit 

 different purposes.

TRUMPET HONEYSUCKLE. See Loni- 



CEUA. 



TUBEROUS ROOTS, such as consist of one 

 or more swelled or knobbed tubers, of a solid 

 fleshy substance. 



In this tribe are comprised many plants of the 

 ornamental flowery kind, and some esculents of 

 the kitchen garden ; as in the former anemone, 

 ranunculus, filipendula, many sorts of iris, aco- 

 nitum, pasony, orchis, cyclamen, winter-aconite, 

 day lily, &c. some also with bulbo-tuberous 

 roots, as gladiolus, polyanthes, or tuberose, 

 ophrys, &c. and of the esculent tuberous roots 

 are the potatoe and Jerusalem artichoke; all 

 of which plants are principally perennial in their 

 roots, being perpetuated annually by offsets. 



TUBS, a sort of boxes calculated for contain- 

 ing large green-house exotics, and other potted 

 plants and trees when grown too large for the 

 pots. 



Green-house plants, particularly in some of 

 the larger-growing sorts, in a few years growth 

 become too large to be contained longer in pots, 

 even in those of the largest size ; which being 

 sometimes both too small for the increased roots 

 of the plants, and of insufficient strength to admit 

 of moving them with the plants, as large orange 

 and lemon-trees, myrtles, oleanders, and other 

 tree kinds, as well as large plants of the great 

 American aloe, &c. : when any of these, or 

 other similar large-growing trees and plants, are 

 advanced considerably in size in their general
