THE FLOWER GARDEN. 
sand. Place the pots in a propagating frame (temperature 
65 to 75 deg.), and keep them there till the seedlings are 
well up, then remove and transfer to 3in. pots, and later into 
4^in. pots. Plant out the sedlings in June, but as the plants 
will necessarily be small the first year, brilliant results must 
not be expected. Cannas to do well outdoors must be grown 
in sheltered positions and in a deep rich soil. They display 
their beauty to the best advantage when grown in beds by 
themselves, or in association with other tropical flowering or 
foliage plants. When grown in beds plant the tall orchid- 
flowered sorts in the middle, and the dwarf, gladiolus-flowered 
ones round the margin. In dry weather an abundant supply 
of water with an occasional application of liquid manure will 
be necessary. In October lift the' plants and store them in a 
frost-proof cellar or under the staging of the greenhouse. In 
March place the roots in pots and start to grow in heat, plant- 
ing out late in May. In the absence of heat the roots may 
be planted direct intp the beds early in May. 
Cedronella (Balm of Gilead). — A half-hardy shrubby 
perennial, native of the Canary Islands, and a member of the 
Sage order (Labiatae). The only species we shall refer to 
here is C. triphylla. This has fragrant foliage, grows 3 to 4ft. 
high, and bears whitish or pale purplish flowers in whorls on 
short spikes in summer. It succeeds best in sandy loam and 
leaf-mould in a well-drained border at the base of a south wall. 
Plant in spring. Increase by seeds sown in gentle heat in 
spring, planting the seedlings out in May. 
Celosia. (Cocks-comb). — Tender annuals, belonging to 
the Amaranth family (Amarantaceae), and natives of India. 
The Cocks-comb proper, with its dense fleshy head of flowers, 
is too formal and uninteresting a plant to grow in the flower 
garden, but the varieties of C. cristata variegata and C. pyra- 
midalis, with their handsome plumes of crimson, red, yellow 
inflorescence, render them desirable plants for massing in beds 
during the summer. Seeds should be sown in a temperature 
of 65 to 75 deg. in February or March, and the seedlings sub- 
sequently planted singly in small pots, grown on in heat till 
May, then hardened off and planted out in June in rich soil and 
kept moist in dry weather. 
Celsia. (Cretan Mullein). — The Celsias belong to the Fox- 
glove order (Scrophulariaceae), and somewhat resemble the 
Mulleins in their general appearance. C. cretica is a biennial 
species, growing 3 to 5ft. high, of a shrubby habit, and bearing 
in summer, on long spikes, bright yellow flowers with purple- 
red spots on the upper petals. This should be treated as an
