A drawing-room is about the worst room for a camellia to be in, when it is in blossom, or in blossom bud. The camellia is an "evergreen," and the roots of evergreens are not so active or so excitable as the roots of other plants; therefore when an evergreen is kept in a warm, comfortable room, the dry, warm air in the room excites the plant or the leaves, flowers, and buds of the plant, faster than is natural for the roots. The roots might, therefore, be immersed in water, and yet the plant want for water at the same time. It is, consequently, essential that blooming camellias, in warm living-rooms, should be constantly and abundantly supplied with water all the time; and they stand in need of rest and refreshment as much and as often as the other inhabitants of drawing-rooms, who may be exercised beyond their powers, at routs, balls, and all the rest of gayeties. The way to rest a camellia in bloom is to put it for so many hours into a much cooler room than a drawing-room; and the way to refresh it is to allow it to breathe the cool night air as long as it is above the freezing point, and not in a " draught." Not that frosty air in motion is hurtful to the camellia itself, but that the delicacy of the flowers cannot hold up against it with impunity.
Those who cannot sleep a " wink " if they retire early to rest, and who keep blooming camellias in the drawing-room, ought to ring every night about half-past ten, to have the camellias taken to "their own room," where they should rest and be refreshed till the drawing-room was "dusted and put to rights " the next day. With that attention, no inmate of the drawing-room will look more fair, or more free and cheerful than the camellia.
