PART II.
[*]Acacia Julibrissin.—A native of Persia, with large and elegant much-divided leaves, and flowers somewhat like short tinted brushes from the numerous purple stamens. Though this does not succeed as a standard tree in all parts of England (where it grows well against walls, and sometimes flowers), yet doubtless it would do so in some parts of the south, and I have seen it make presentable standards about Geneva and in Anjou. But for our purposes it is better that it should not be perfectly hardy, as by confining it to a single young stem and using young plants, or plants that have been cut down every year, we shall get an erect stem covered with leaves more graceful than a fern, and that is the kind of ornament we want as a graceful object amidst low-growing flowers. The leaves, like those of some other plants of the pea tribe, are slightly sensitive. On fine sunny days they spread out fully and afford a pleasant shade; on dull ones the leaflets fall down. This interesting phenomenon takes place with other members of the same family—for instance, the elegant A. dealbata of our conservatories. Seed of A. Julibrissin—or the silk-rose, as it is called by the Persians in consequence of its silky stamens—is readily obtained, and it is much better raised from seed, as then you get those single-stemmed and vigorous young plants which are to the flower-garden what an elegant fern is to the conservatory or show-house. To succeed with it in the way above named, it may be protected at the root and cut down every year in spring, or strong young plants may be put out annually, in much the same way as those of A. lophantha.
[*] The names of all hardy species and other kinds easily raised from seed in spring (the kinds useful in all classes of garden), are preceded by an asterisk.
Acacia lophantha.—This elegant plant, though not hardy, is one of those which all may enjoy, from the freedom with which it grows in the open air in summer. It will prove more useful for the flower-garden than it has ever been for the houses, and, being easily raised, is entitled to a place here among the very best. The elegance of its leaves and its quick growth in the open air make it quite a boon to the flower-gardener who wishes to establish graceful verdure amongst the brighter ornaments of his parterre. It has graceful fern-like leaves and a close and erect habit, which permits us to closely associate it with flowering plants without in the least shading them or robbing them. Of course I speak of it in the young and single-stemmed condition, the way in which it should be used. By confining it to a single stem and using it in a young state, you get the fullest size and grace of which the leaves are capable. Allow it to become old and branched, and it may be useful, but by no means so much so as when young and without side branches. It may be raised from seed as easily as a common bedding plant. By sowing it early
