H. arborescens, but with large blue flowers ; and H. stellata 
whose barren flowers are double, and light blue or pink. 
According to Siebold this H. japonica has two varieties, 
called Benikaku, with rose-coloured flowers; and Konkaku, 
with pale blue flowers. It does not grow more than two feet 
high at the most, branched from the very bottom. The 
Japanese cultivate it commonly in their gardens. It is found 
wild on the mountains of Nipon. 
A hardy shrub, very much resembling, and requiring the 
same kind of treatment as, the common Hydrangea hortensis. 
It grows freely in a mixture of loam and sandy peat, to which 
is added a small portion of decayed cow-dung. 
It is easily increased by cuttings of the young wood, after 
the plant has flowered in July. ‘The cuttings should be put 
in sand, and placed in a mild heat, and kept close for two or 
three weeks. It flowers from May to July, and was presented 
to the Society by Mr. H. Low, of Clapton, who imported the 
first plants.
