It is a well-known fact that this fine Australian creeper is bad to manage on its own roots, being very impatient of water, and liable to damp off, especially in dull weather. Being anxious to have some specimens of this most beautiful Clianthus, it occurred to me that by grafting it on some of the less delicate varieties we might have better plants. Last July I grafted this Clianthus on a very strong-growing variety, the name of which I do not know. The result is very satisfactory; and I would recommend those who have a difficulty in growing this plant well to graft it on Clianthus puniceus, or any of the other varieties, and I am sure they will not be disappointed in having good plants, either trained in the balloon shape for pot-culture, or planted in the border of an intermediate house. The mode of grafting is very simple and effective. The stock and scion being both in a growing state, but having just acquired a woody consistency at the part to be operated on, an oblique cut is made on the stock, and the scion being made in the form of a wedge, so as to fit the incision as exactly as possible, the part is then tied up with a piece of matting.
The plant may then be put into a moderately warm, close, and shady place, and in the course of three weeks or a month the scion will begin to grow, after which the top of the stock may be cut off down to the part where the union has taken place. Richard.
