74 THE CENTURY BOOK OF GARDENING. 



them require a stove, but many will thrive in a greenhouse, 

 the best of them being : Campbelli, purple ; coerulea, 

 blue ; coerulea Constance Elliot, white ; ccerulea race- 

 mosa, red ; Lawsoni, light purple ; and Imperatrice 

 Eugenie, reddish purple. Should be planted in a 

 border. 



Plumbagos. — The Plumbago capensis is one of the most 

 charming of all climbers for the greenhouse, and will 

 succeed in structures heated just sufficiently to keep out 

 frost. It bears flower clusters of a pretty blue colour, and 

 so profusely that when in full beauty a plant is surfaced 

 with blossom. The Plumbago need hardly be described, 

 as it is familiar in most gardens, but some may not grow 

 or know it. The variety alba has white flowers. Cuttings 

 may be readily struck in the spring, and require a 

 temperature of about 6odeg. , placing them in pots filled 

 with ordinary soil for cuttings in the usual way. When 

 the cuttings are ready — and put no more than five or six in 

 a 5m. pot — remove to the house and put a hand-light over 

 them to promote quick rooting. When rooted transfer 

 singly to 3m. pots, and keep rather close until established. 

 After this give air abundantly, for the Plumbago must not 

 be coddled in any way. They may be grown on in pots 

 or planted out ; the latter method is, perhaps, the best, 

 thoroughly well draining the border. During the winter 

 reduce the supply of water considerably. 



RhodOChitOn VOlubile.— A slender yet free-growing 

 climber whose dark red-coloured flowers protrude from a 

 widely-expanded calyx, thus giving it a very distinct 

 appearance. The flowers are produced in great profusion 

 throughout the summer months, when the slender shoots 

 are wreathed for a considerable distance with them. 



Rhynchospermum jasminoides. —White Jasmine-like 



sweet-scented blossoms, borne during the summer. 

 RUSGUS androgynus. — One of the most vigorous of all 

 greenhouse climbers, bearing a profusion of long pinnate 

 leaves of a stout leathery texture and of a deep green 

 colour. It is suitable for planting in draughty places, 

 as harsh dry winds have little effect upon it. This Ruscus is 



used with good effect at the Crystal Palace, where it climbs 

 up the pillars and roof. The flowers are inconspicuous. 

 Solarium jasminoides. — A most prolific flowerer, the 

 clusters of blossoms, which are white slightly tinged 

 with blue, being borne in great profusion from spring to 

 autumn. In the South of England this succeeds out of 

 doors. It is no uncommon sight to see cottages in 

 Devonshire and Cornwall wreathed in it. 



Sollya heterophylla and S. parviflora. — Two 



slender twining plants with narrow deep green leaves, 

 and a profusion of small drooping bell-shaped blossoms of 

 a pleasing shade of bright blue. 



TaCSOnia. Nearly related to Passiflora, but some have 

 even more showy blossoms. They hang down supported 

 by very long flower stalks, hence are on a roof seen to very 

 great advantage. A selection would include : Exoniensis, 

 rich carmine pink ; mollissima, pink ; Smytheana, light 

 red ; Van Volxemi, scarlet, shaded violet. 



TeCOma. — All these need to be thoroughly exposed to the 

 sun to induce them to flower, and when this is the case 

 they are remarkably showy. The best are : T. capensis, 

 orange scarlet ; T. jasminoides, white, red throat ; T. 

 Smithi, orange ; and T. stans, yellow. 



Thunbergia alata is a beautiful annual climbing plant 

 of which there are several varieties, the showiest of them 

 being those forms in which the flowers are some shade 

 of yellow, with a dark centre. Sow in spring in gentle 

 heat, and grow on quickly afterwards. 



Tropseolum. — There are two quite distinct classes of 

 Tropseolum, both of which form good climbing plants 

 for the greenhouse. The first has tuberous roots and 

 throws up annual shoots, which flower, and after that the 

 tuber has a period of rest. To this section belong 

 T. azureum, blue ; T. brachyceras, yellow ; T. Jarratti, 

 scarlet and yellow ; and T. tricolorum, red and black. 

 The second class consists of forms of the Nasturtium which 

 are valuable for winter blooming. Good kinds are Ball 

 of Fire, scarlet ; Clapham Park, orange ; and Hermine 

 Grasshoff, double, orange scarlet.
