HARDY BIENNIALS.--Biennials live through one winter period. They require to be sown in the summer months, about June or July, in order to get established before winter; they should be pricked out as soon as large enough, and should have ample space so as to become hardy and stocky. They should be planted in good soil, but not of too stimulating a character. Those that are perfectly hardy are best planted where they are to flower in good time during autumn. This transplanting acts as a kind of check, which is rather beneficial than otherwise. Of those that are liable to suffer injury in winter, as the Brompton and Queen Stocks, a portion should be potted and wintered in cold frames ventilated as freely as the weather will permit.
The number of biennials is not large, but a few very desirable garden plants, such as the following, occur amongst them:--
_Agrostemma coronaria_ (Rose Campion): hardy, 1½ ft., bright rose-purple or rose and white.
_Beta Cicla variegata_: hardy, 2 ft., beautifully coloured leaves and midribs, crimson, golden, &c.
_Campanula Medium_ (Canterbury Bell): hardy, 2 ft., blue, white, rose, &c. The double-flowered varieties of various colours are very handsome.
