Paulownia

Paulownia - P. imperialis 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 exceeded 20 inches. 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 beautiful, and much used in public gardens and even in street planting. At maturity the Paulownia assumes a dense rounded head, but rarely exceeds 30 feet 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 enormous leaves, with the advantage 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.
