Summer and winter flowers

As a general principle for regulating the plants in this figure, the winter and spring flowers ought, as much as possible, to be of sorts which admit of being in the ground all the year: and the summer crop should be planted at intervals between the winter plants. Or the summer crop, having been brought forward in pots under glass, or by nightly protection, may be planted out about the middle of June, after the winter plants in pots are removed. A number of hardy bulbs ought to be potted and plunged in the beds in the months of October and November; and when out of bloom, in May or June, removed to the reserve garden and plunged there, in order to perfect their foliage and mature their bulbs for the succeeding season.* (* Ency. of Gardening, 1000.)
