must not be overlooked, for they comprise two particularly valuable 

 plants in montana and Jackmanii, and several others of much im- 

 portance. There is no more beautiful creeper than the Flame 

 Nasturtium, the Tropaeolum speciosum of botanists; but it will 

 not thrive in dry, hot positions. It must have root and atmospheric 

 moisture to give its true beauty. Climbers and creepers sometimes 

 fail because they are planted in a position where they catch drip 

 from a roof. This should be avoided, if necessary by planting 

 rather farther from the wall, and then training in. An annual 

 mulching of manure helps the plants. In most cases pruning takes 

 the form of thinning out the older growth to make room for younger 

 wood. In a few cases, notably the Wistaria, the young wood is 

 spurred to older branches. Climbers must also be selected for arches, 

 pillars, pergolas, and summer-houses (see Flower Garden). The 

 following selections may be useful :

All of the plants are dealt with under their own names. 



Clivia, Imantophyllum (cli-vea, after a member of the Clive 

 family. Ord. Amaryllideae) . See Bulbs. 



Cobaea (co-baea, after Senor Cobo. Ord. Polemoniaceae) . Only 

 one member of this genus is grown to any extent, and that is 

 scandens, a rambler bearing purple flowers in summer (see the 

 Botanical Magazine, t. 85 1). There is a variety with white-margined 

 leaves. It is suitable for the roof of a cool house, or for pillars out- 

 side in summer, and the best plan is to treat it as an annual, sowing 

 in heat in spring, hardening in a frame, and planting out in June. 

 Ordinary soil.
