One point in the successful culture of Schizanthus should never be forgotten.  The roots must not be allowed to become pot-bound.  Where this is permitted at any stage of growth it is fatal to the development of a handsome show of bloom.

==Senecio elegans==

==Jacobea.  Hardy annual==

Among the double varieties, the crimson, purple, rose and white Senecios take the lead for beauty and usefulness.  They are remarkably accommodating plants, adapted for beds or the greenhouse.  Sow early in pans or boxes, give the seedlings liberal treatment, and when bedded out the plants will produce myriads of bright flowers, until frost puts a stop to them.  Any good soil which does not become pasty will suit, and full exposure to sunshine is essential to the production of a rich display of colour.  In March or April seed may safely be sown in the open ground.

The Tall Single Bright Rose Jacobea is invaluable as a cut flower for table decoration under artificial light.  It rivals the Star Cineraria in form and, being a hardy annual, it may be grown with the utmost ease.

==Silene==

==Catchfly.  Hardy annual==

Not one of the hardy annuals has established a better claim to be sown in autumn than the Silenes.  Alone, they make a very attractive display, and they can be used with especial effect in beds planted with Daffodils, Hyacinths, and Tulips.  While the Daffodils are in full beauty the Silenes clothe the ground with a carpet of green, and after the foliage of the bulbs has been cut off or pinned down the Silenes furnish a fresh display of floral beauty in advance of the summer bedders.

Silenes do not thrive on heavy damp soils, but the difficulty can be surmounted by keeping the plants in pans or boxes under a cold frame until growing weather sets in.  The plants do very well in loam, and best of all in a dry sandy soil.  The spring sowing should be made in March or April; the autumn sowing in August or early in September.

==Solanum==

==Annual and perennial; half-hardy==

Solanums are of importance, some as greenhouse plants, and others as sub-tropical bedders.  They are somewhat tender in constitution, and must have good cultivation in a light rich soil.  A sharp look-out for red spider is necessary, for this pest is very partial to Solanums.  March is early enough to sow the seed, but for ordinary purposes April is to be preferred.  By the middle of June the plants should be strong enough to put out, and with genial weather will make rapid progress.  Those grown for their berries may be sown from February onwards, as it is important to secure bushy plants before they begin to flower, and an early start insures an early ripening of the bright, handsome fruit.
