The Garden Under Glass

OUTDOOR PLANTS IN GREENHOUSE 127 Stocks, good varieties among them being Crimson King, Beauty of Nice, Riviera Market and Queen Alexandra. Sweet-peas.—By gentle forcing, sweet-peas may be had in flower in April and May. Sow seeds in September in boxes or pots and put five or six in large pots about Christmas. By keeping them in a cold, light, airy house and staking them when they need it, they will produce quite a good supply of flowers before they can be had outside. Verbenas.—When grown for the greenhouse these are best propagated by means of cuttings rooted under cold conditions in the autumn, or over a hotbcd in the spring. The great enemy is mildew, which may be kept in check to some extent by dusting flowers of sulphur over the foliage. Verbenas come fairly true from seed—even that beautiful variety, Miss Willmott, can be had almost true to colour from seeds. These should be sown quite early in the year. Violas.—Though not often grown in the greenhouse, violas would be a pleasing picture there for a change. For this purpose cuttings should be rooted in July or August and grown along three in a pot to flower in a 5-inch or 6-inch pot. Keep them as cool as possiblc without actually being in a cold frame. Violets.—Violets are usually grown in frames, though they do remarkably well in pots. Split up the old plants when they have finished flowering in the spring and plant them in good, rich, deeply trenched soil, where they will get partial shade. Here they may remain until August, when the frame should be prepared for them. Put a load of heating material in the bottom, and after treading it firmly, cover with good rich soil, setting tlie plants about nine inches apart at such a lieight that the leaves nearly touch the glass. Keep the liglits off on all warm days
