they should be potted off,
planting them out again in the spring. The annual and biennial kinds
merely require to be sown in the open border. Most of the Rockets give
forth greater fragrance towards evening. Their flowering season is
June. Height, 1 ft. to 1-1/2 ft.

Rock Rose.--_See_ "Cistus" _and_ "Helianthemum."

Rodgersia Podophylla.--A hardy perennial having immense bronze
foliage. It thrives best in a moist, peaty soil; flowers from May to
July, and may readily be increased either by seed or division. Height,
3 ft.

Rogiera Gratissima.--A pretty evergreen stove shrub, which is often
trained to a single stem so as to form a standard. It succeeds in
sandy loam and peat. It may be sunk in the flower-border during the
height of summer, but must be taken indoors before frost sets in.
Cuttings placed in sand under a hand-glass in heat will strike. It
flowers in June. Height, 3 ft.

Romneyi Coulteri.--This grand white-flowered Poppy Tree is quite
hardy, and will grow in any light, rich soil. It blooms in August and
September, and may be increased by seed or by division. Height, 4 ft.

Rose Campion.--A pretty hardy perennial which may be grown from seed
sown in autumn, choosing a sheltered site, or in March in a frame or
under a hand-glass, transplanting it in the autumn into a light, rich,
loamy soil. Height, 2 ft.

Rosemary (_Rosmarinus Officinalis_).--This hardy evergreen shrub
should occupy a dry and sheltered position. Its fragrant purple
flowers are produced in February. Cuttings of the ripened wood, if
planted in spring, will strike root freely. Height, 2 ft.

Roses.--A good, deep, loamy soil, well drained, but which retains a
certain amount of moisture, is the most suitable. The position should
be sheltered, yet open and exposed to the sun. The latter part of
October or November is the most favourable time for planting, but
it may be continued with safety until the commencement of March. A
fortnight before planting the holes should be dug out 1-1/2 or 2 ft.
deep, and plenty of old manure thrown in and trodden down. On this a
good layer of fine mould should be placed, so that the roots do not
come in contact with the manure. Great care must be taken not to
expose the roots to the cold air. When the ground is quite ready for
their reception dip the roots in a pail of water, then spread them out
carefully on top of the mould, fill in the earth, and tread it
firmly. If the plants are standards they require to
