Senecio Pulcher (Noble Crimson Groundsel).—­A warm position and a deep, rich, well-drained soil are needed for this flower.  It may be propagated by cutting the roots into pieces 5 or 6 in. long, and dibbling them into light soil.  It is also increased by the rootlets, which send up small growths in spring.  Protect from damp and frost, and keep a sharp look-out for slugs.  The flowers are produced in autumn.  Height, 3 ft.

Senna, Bladder.—­See “Colutea.”

Sensitive Plant.—­See “Mimosa.”

Shallots.—­Plant the bulbs in November, or in February or March, in rows 9 in. apart, and the bulbs 6 in. one from the other.  In July, when the tops are dying down, lift the bulbs, lay them in the sunshine to dry, then store them in a cool place.

Shamrock.—­See “Trifolium Repens.”

Sheep Scabious.—­See “Jasione.”

Shortia Galacifolia.—­A hardy, creeping Alpine evergreen, having oval leaves, slightly notched at the margins, which turn to a brilliant crimson during the autumn and winter months.  In April and May it produces pearly-white flowers, somewhat Campanulate in form.  It may be planted in early autumn or spring.  A light, rich soil suits it best, and it delights in partial shade.  It is a lovely plant for rock-work.  Height, 6 in.

Shrubs.—­Deciduous shrubs may be transplanted at any time during late autumn or winter when the ground is not too wet.  Evergreen shrubs may be moved either early in autumn or in April or May, damp, warm, but not sunny weather being most suitable for the operation.  They rejoice in a clean, healthy soil, such as good loam; animal manure does not agree with them, but wood ashes, or charcoal powder with a little guano, may be used.  Cuttings of shrubs or trees may be taken in September, placed in a mixture of sandy loam and leaf-mould with 1/2 in. of sand on top, and covered with a hand-glass; 5 to 8 in. is a good length for the cuttings, all of which, with the exception of about 1 in., should be buried, and preferably with a heel of old wood.  Keep the soil just damp and give shade.

Shrubs for Lawns.—­Monkey Puzzle (Araucaria Imbricata)—­mix wood ashes and burnt refuse with the soil; Thujopsis Delabrata, Thujopsis Borealis (of taller growth), Irish Yews, Cupressus Lawsoniana Erecta Viridis, Thujas Orientalis, Vervaeneana, Semperaurescens, Standard Rhododendrons, Standard and Pyramid Hollies, Yucca Gloriosa (a perfect picture), Yucca Recurva (the best hardy plant for vases).  The Cercis tree is also well adapted for lawns.

Sicyos.—­This hardy annual somewhat resembles the Cucumber, but is scarcely worth growing except as a curiosity.  The seeds are sown on a hotbed in spring, potted off when strong enough, and transferred to the open border early in June.  It is a climber, and flowers in August.  Height, 3 ft.

Sidalcea.—­Very pretty hardy perennials, of easy culture.  S. Candida has pure white flowers closely arranged on the upper part of the stems.  S. Malvaeflora bears beautifully fringed, satiny pink flowers.  They will grow in any good soil from seed sown in autumn and protected during the winter, or they may be increased by division of the roots.  Height, 3 ft.
