group, and the freest in growth and flower. Bright yellow is the colour 

 of its pea-shaped flowers. 



Carpentaria californica. Wherever this charming Californian 

 shrub can be successfully grown it should be represented, as it bears beauti- 

 ful flowers. It delights in peat, loam, and leaf-mould in equal proportions, 

 and good drainage is of great importance. Be careful, too, not to expose 

 it to cold east and north-east winds, as these do considerable damage to 

 young growth. It grows about a dozen feet in height, and has greyish- 

 green leaves, whilst its sweet-scented, pure white flowers with conspic- 

 uous golden-yellow stamens in the centre, are produced in clusters at the 

 points of the growths in June. 



Cassandra calyculata (Andromeda calyculatd). A freely-branched, 

 low-growing North-American shrub, producing a good effect when planted 

 in large masses near the edge of water, as it succeeds best in a cool, moist 

 root-run. Its wiry shoots are clothed with small bright green leaves, 

 and in early spring small bell-shaped flowers appear in quantity. It is 

 thoroughly hardv and prefers full exposure to partial shade. 



Cassinia flllvida, also known under the name of Diplopappus chryso- 

 phyllus, hails from New Zealand, and forms a medium-sized, much branched 

 shrub, with slender bright yellow stems and tiny green leaves, bright 

 yellow on the under sides. It bears creamy- white flowers in terminal 

 panicles in autumn, and these are conspicuous for two or three months. 

 It is a good seaside shrub, and an open sunny spot favours good growth 

 and the production of flowers. 



Catalpas are handsome trees for the garden, delighting in poor 

 soils, and flowers appear when few trees and shrubs are in bloom. They 

 are excellent for planting on the lawn, and can be well recommended for 

 towns. C. bignonioides , not infrequently called syringcefolia, the well- 

 known Indian Bean Tree, is a North-American species of vigorous growth, 

 and often reaches twenty-five feet high, with a dense-spreading head. 

 Its V-shaped leaves are bright green, flushed with bronze towards the 

 margins, and quite downy on the under sides. During summer it bears 

 at the branch tips erect spikes of blush white flowers, suffused with violet 

 and purple in the yellow throat. It is very free. The golden-leaved 

 variety (aiirea) is less vigorous, but exceedingly ornamental. It is a 

 yellow-leaved counterpart of the type, and may be planted in the shrub- 

 bery or as single specimens on the lawn with telling effect, and if the 

 shoots made during the previous year are cut hard back in February the 

 foliage is larger and richer in colour. C. cordifolia (C. speciosa) is even 

 more ornamental than the first named, and perfectly hardy. It also 

 blooms early, and the flowers are larger and brighter in colour. It is 

 free in growth, and a first-rate shade tree. Catalpas like moisture, 

 and this is the reason why the trees are so luxurious and shapely in the 

 gardens of the Thames valley. Several new species have been received 

 from China during the present century, which differ from the older kinds 

 by having rosy-purple or reddish-purple flowers. Two of the best are 

 C. Fargesii and C. Daclouxii.
