43.  Saxifraga oppositifolia.  Purple saxifrage.—­Perhaps we have few flowers early in the spring that deserve more attention than this.  It blooms in the months of February and March, and in that dreary season, in company with the Snow-drop, Crocus, and Hepaticas, will form a most delightful group of Flora’s rich production.  The Saxifrage is a native of high mountains, and it can only be propagated by being continually exposed to the open and bleakest part of the garden:  it succeeds best in pots.  It should be parted every spring, and a small piece about the size of a shilling planted in the centre of a small pot, and it will fill the surface by the autumn.  The soil bestsuited to it is loam.

44.  Sedum acre.  Stone crop.  Sedum rupestre.  Rock ginger.—­All the species of Sedums are very ornamental plants, and are useful for covering rocks or walls, where they will generally grow with little trouble.  The easiest mode of propagating and getting them to grow on such places is first to make the place fit for their reception, by putting thereon a little loam made with a paste of cow-dung; then chopping the plants in small pieces, and strowing them on the place:  if this is done in the spring, the places will be well covered in a short time.

45.  Statice Armeria.  Thrift.—­This plant is valuable for making edgings to the flower garden.  It should be parted, and planted for this purpose either in the months of August and September, or April and May.

46.  STIPA pinnata.  Feather grass.—­We have few plants of more interest than this; its beautiful feathery bloom is but little inferior to the plumage of the celebrated Bird of Paradise.  It is frequently worn in the head-dress of ladies.

47.  SWERTIA perennis.  Marsh SWERTIA.—­This is a beautiful little plant, and worth the attention of all persons who are fond of flowers that will grow in boggy land.  It is a perennial, and of easy culture.

48.  Trollius europaeus.  Globe flower.—­This is also a fine plant:  when cultivated in a moist soil its beautiful yellow flowers afford a pleasing accompaniment to the flower border and parterre in the spring of the year.  It is easily raised by parting its roots.

49.  Tulipa sylvestris.—­This beautiful flower is also an inhabitant of our flower-gardens; it is called the Sweet-scented Florentine Tulip.  It has a delightful scent when in bloom, and is highly worthy the attention of amateurs of flower gardens.  It should be planted in September, and will grow in almost any soil or situation.

50.  TYPHA latifolia.  TYPHA angustifolia.  TYPHA minor.—­These are all very fine aquatics, and worth a place in all pieces of water; the foliage forms a fine shelter for water-fowl.

51.  Viola tricolor.  Heart’s-ease.—­Is an annual of singular beauty, and forms many pleasing and interesting varieties.
