but the aroma, which is pregnant with opium, renders too many
of them unpleasant for the garden.

39. POLEMONIUM coeruleum. GREEK VALERIAN, or JACOB'S LADDER.--Is also a
beautiful perennial, and claims the notice of the gardener. Its
variety, with white flowers, is also ornamental. It is raised
from seeds, which are sold in plenty in our seed-shops.

40. PRIMULA officinalis. COWSLIP. PRIMULA vulgaris. PRIMROSE. PRIMULA
elatior. OXLIP. PRIMULA farinose. BIRD'S EYE.--All well known ornaments
of numerous varieties, double and single. The third species is the
parent of the celebrated Polyanthus. The last is also an interesting
little plant with a purple flower. It grows best in bog earth.

41. ROSA rubiginosa. SWEET BRIAR.--This lovely and highly extolled shrub
has long claimed a place in our gardens. We have several varieties with
double flowers, which are highly prized by the amateurs of gardening.

42. SAXIFRAGA umbrosa. LONDON PRIDE.---A beautiful little plant for
forming edgings to the flower garden, or for decorating rock-work.

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
