A writer in the Gardners' Chronicls says: "If taste and a knowledge of colors are observable in the distribution of the plants in the flower borders, we may also perceive a certain degree of skill in the peculiar method practised in France of pruning and managing the Persian lilacs and the few other shrubs that are cultivated. The roses and honeysuckles are annually headed back and pruned very close to the stem. The lilacs are nice bushy half standards, having their branches so thinned and regulated that none either cross or interfere with each other, nor extend beyond a certain distance from the stem. In the winter pruning, all the young twigs are removed except the one at the end of the branch that is left for flowering, and towards the end of April and beginning of May, they have a splendid appearance. Immediately the flowers decay, the twigs that bore them are pruned back, and the branch made to send out a fresh shoot for flowering the following season; by this mode of treatment the bunches of flowers, although by no means so numerous, are very much larger and finer than any we are accustomed to see".
