Among the many old and beautiful flowering plants, which from some cause are almost neglected, except by here and there a devoted lover of old as well as new plants, the Eranthemum pulchellum holds a very high position.
It is generally treated as a stove plant, and but seldom seen in perfection. We have great pleasure in using our efforts to bring into notice this most beautiful plant, because it is, when properly treated, a most lovely and interesting object; and more especially as it is one of a great number of good old plants which have been displaced by such as possess novelty, but in many instances little ornament.
During the month of March, or April, select some half-ripened wood as cuttings, placing them round the edge of a pot, in good sandy soil. Place the pots in a gentle hotbed. Soon as rooted, place them in pots according to the amount of roots, being careful not to over-pot them; return them again to the hotbed. When they commence growing, pinch out their tops, when they will soon commence throwing out lateral shoots. They must be shifted again, as soon as the roots show themselves through the bottom of the pots, into pots two sizes larger than the ones in which they have been growing; and when the lateral shoots have made some three or four joints, these joints must also be taken off, when they will again throw out more laterals: by this means a handsome, bushy plant will be obtained, of from one foot to eighteen inches in height. This, under ordinary circumstances, will be about the beginning of June, when the plants must be removed to a cool frame, and plunged in old leaves Or spent tanners' bark, protecting them from heavy storms of rain, and being careful not to supply them with too much water.
In this situation the shoots will become well matured, and the plant will become dormant early in the fall. They may be kept in the frame as long as there is no danger to be apprehended by frost. They should be removed a few at a time into the forcing-house, having been previously repotted into pots which will contain about half an inch of fresh soil around their roots., Supply liberally with water with frequent syringings overhead.
The result of this treatment will be beautifully-shaped plants, with four shoots, each of which will produce three lovely clusters of blue flowers.
The soil in which the Eranthemum flourishes is equal parts of good fibrous loam, sandy peat, and good rotten leaf mould.
There are but few plants the cultivation of which is more simple, and but few that are more beautiful; and where forced flowers are in request during the winter months, but few more desirable.
[A well-timed effort on behalf of an old, but really beautiful plant. We hope Mr. Barker will continue his labors in this direction. Many of our "old worthies" are too much neglected. - Ed].
