In this way all those kinds growing in chalk may be made to grow; but
such as the Orchis moryo, maculata, and pyramidalis, may be grown in
loam alone, planted in pots in the common way. Care should be taken that
the pots in which they are planted are protected from wet and frost in
the winter season.
37. ORNITHOGALUM latifolium and umbellatum are also ornamental, and are
often cultivated for their beautiful flower. The season for planting the
bulbs is about the month of September.
38. PAPAVER somniferum. GREATER POPPY. PAPAVER Rhoeas. CARNATION POPPY.
--These are made by culture into numerous varieties, and are very
beautiful; 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.
