Passiflora Constance Elliot. 



is best for it, though it grows 

 against west or east walls, only 

 requiring a good soil, and, per- 

 haps, a slight protection during 

 winter. In places where it 

 fruits freely the bright orange 

 colour continued far into au- 

 tumn is an added merit. To 

 ensure fruiting, several plants 

 should be planted not far from 

 one another. The white 

 variety, Constance Elliot, is as 

 hardy as the older kind. No 

 other variety of P. ccerulea is 

 so distinct, and no other Pas- 

 sion-flower is hardy enough 

 for outdoor walls. The blue 

 kind may be grown from seeds, 

 and flowers from the second 

 year ; the white one strikes 

 easily from cuttings. The blue 

 Passion-flower first came from 

 Brazil two hundred years ago. 



PAULOWNIA. P. impe- 

 rialis is a fine flowering tree 

 from Japan, not suitable for our 

 climate generally, though in a 

 few places it succeeds. It 

 comes into flower and leaf so 

 early that the buds and often 

 the young leaves are injured 

 by late frosts ; otherwise there 

 may be a lovely bloom. It is 

 fine in leaf as well as in 

 bloom ; the leaves are a foot 

 in length, and have even ex- 

 ceeded 20 in. The flowers are 

 in erect spikes, and shaped 

 like those of a Bignonia of a 

 delicate mauve purple, blotched 

 inside with a deeper tint. In 

 countries a little warmer than 

 Britain this tree is very beauti- 

 ful and much used in public 

 gardens and even in street 

 planting. At maturity the Paul- 

 ownia assumes adense rounded 

 head, but rarely exceeds 30 ft. 

 in height, although in some 

 south-coast gardens there are 

 trees of 40 feet. 



If the young trees are cut 

 back annually, they make 

 strong shoots bearing enor- 

 mous leaves, with the advan- 

 tage of being much hardier 

 than the tender greenhouse 

 plants used in summer to give 

 such effects. The tree is best 

 on a light deep loam.
