Parties having large conservatories or entrance halls to decorate in the autumn, will find this one of the most useful plants, treated as under. If commencing with a young plant, it must be grown on as much as possible the first year, keeping it to one stem; and if anything like justice has been done, it will attain a considerable height, so that the next season's routine may be taken as the annual one. In March or April cut this back to (say) five or six feet, according to the height required, allowing from three to four for the growth of the young shoots before branching out. Shake it out, and repot it in a proportionate sized pot, giving it nothing but well-decayed melon ground dung, in lumps, and a little sand; if convenient to the parties, give a little bottom heat, that by having a stock it gives earlier bloom; but this is by no means necessary to success; when it begins to break all the shoots but one must be rubbed off: in this and the dung, I consider, lies the secret For three months I have seen from twenty to eighty blooms out every morning on this young shoot, filling the air with perfume.
The older the plant the more certain the success as to large blooms and rich dark leaves. - J F„ in Florist.
