This is by far the / best addition which has been made of late years to our hardy forcing shrubs. We hear and see a good deal of the French productions in the way of white Lilac, but their plants are large before they are fit for their method of forcing. Here, however, we have a sort that will in a short time supersede that, with all persons who require to force, since it sets its buds on small plants, and opens freely. We have some plants eighteen inches high, with a dozen clusters of bloom, and if forced in a shady house, it comes a good white. When it is more plentiful, and the plants get up to, say, three feet or so in height, there will be no more showy plant for a greenhouse. A good deal more has been made of the French practice of forcing white lilac than it deserves. In fact, if a demand were to spring up for it in our markets, a good supply would soon follow, because if the tops are cut off, and put in with bloom-buds well set and ripened, they will push their bloom as fine and as good as whole plants, supposing always that they are forced in some sort of dark house, say a cellar-like mushroom-house. -Florist and Pomologist.
