History, Use, Propagation, Culture, 
1756. Bellis. So called from bellus, pretty. Every one knows the daisy. 
1757. Bellium. See Bellis, from which this genus differs chiefly in the pappus of the grains. 
1758. Dahlia. Named after Andrew Dahl, a Swedish botanist, and pupil of Linnteus. Continental botanists 
call the genus Georgina. This genus grows in Mexico, in sandy meadows, and till the peace of 1814 was 
more cultivated in France than in England : at present it is one of the most fashionable hardy plants. Though 
its leaves are coarse, resembling those of the common dwarf elder, yet the flowers are showy, and continue in 
beauty till late in autumn. The plants grow freely in any soil or situation ; but the poorer the ground is, the 
smaller the size of the plant, and the earlier and more abundant the flowers. The single-flowered varieties 
of D. superflua are almost without end ; the double varieties of both species are much less numerous. Any 
number of the former may be raised from seeds, which ripen in abundance, and if sown in February on 
artificial heat, and transplanted in the end of April, they will flower in the July or August following. The 
double varieties are increased by dividing the roots, or by grafting, or by cuttings ; they may also be some- 
times raised from seeds. A very general way in which both kinds are propagated is by cuttings. They may 
be either taken from the root-shoots in spring, or the tops of the young shoots early in summer ; the lower end 
of each cutting should be cut smoothly off in the middle of a joint, and all the leaves left on, excepting those 
that would be buried in planting the cutting. If planted in sandy soil, on a gentle bottom heat, and covered 
with a hand-glass, they will soon strike root, and produce both flowers and tubers the same autumn. The 
double sorts are grafted on tubers of the single varieties much in the manner of whip-grafting, but without a 
tongue. There must be no buds on the tuber ; cut off a slice from the upper part of it, in a sloping direction, 
and make, at the bottom of the part so cut, a ledge, whereon to rest the graft ; next, cut the scion sloping to 
fit, it should contain two joints, and be cut so that one of these may be at the bottom of it to rest on the ledge ; 
from that joint the scion will occasionally put forth roots; from the other the future stem will be formed. 
Having tied the graft, clay it as in common grafting ; then put the root in fine mould, burying half the graft, 
and place the pot in a gentle moist heat under a glass. If this be done in March, the plant may he shifted 
into a larger pot in April, and planted out in the end of May. 
As the Dahlia is a bulky plant, it requires either to be grown in a very large pot, or in from three quarters 
to a yard and a half of surface. They look well in rows, or occurring singly in a shrubbery. 
The treatment of the Dahlia bears a considerable resemblance to that of the potato and the marvel of Peru ; 
as soon as the frost has blackened the tops of these three plants, their roots require to be taken up, and
