Propagation and Culture. The fir ft and fecond forts are 
troubleiome weeds in gardens, and fhould be rooted out 
with great care. Every fmall piece of the root will 
grow, and therefore it is difficult to deftroy them. With 
refpect to the fecond fpecies, Mr. Miller obferves, that 
being general ly among trees and fhrubs, or under hedges, 
the roots are fo intermixed, that it cannot eafily be ex¬ 
tirpated ; but in an open clear fpot of ground, where 
the plants are carefully hoed down for three or four 
months, they may effectually be deftroyed ; for when 
the ftalks are broken or cut, a milky juice flows out, 
and the roots are foon exhaufted and decay-. On the 
contrary, Mr. Curtis remarks of the i rft fpecies, which 
is the weed that infefts arable lands,'that the more he 
cut and hoed it, the more it fpread and the fafter it grew. 
In effedt, it cannot be eradicated without repeated 
ploughing in dry weather, and then picking out the 
roots and burning them. 
Scammony is a hardy plant, and will thrive very well 
in the open air in Englafid, on a' dry foil. Sow the feeds 
in the fpring on a border of light earth ; keep the plants 
clean from weeds, and thin them to the diftance of three 
feet. The ftalks decay in autumn, but the roots will 
abide many years. 
Purple bindweed, commonly called by gardeners con¬ 
volvulus major, is propagated by fowing the feeds in the 
fpring, upon a warm border, where the plants are de- 
flgned to remain. Some tall flakes muff be placed by 
them, for the ftalks to twine aboutj'otherwife they will 
fpread on the ground, and make a bad appearance. 
Spanifh potatoe is cultivated in warm climates by the 
roots, in the fame manner as our common potatoe, but 
requires much more room, for the trailing ftalks extend 
four or five feet every way, fending out large tubers, 
forty or fifty of which are produced from a Tingle root. 
In England, the roots.mult be planted on a hot-bed in 
the fpring, and if the plants are kept covered in bad 
weather with glades, they will produce flowers, and 
many fmall roots from the joints; but if they are ex- 
pofedto the open air, they feldom make much progrefs. 
Canary bindweed fometimes ripens feeds here, but 
being eafily propagated by layers or cuttings, the feeds 
are not much regarded. Thofe plants, however, which 
are raifed from layers or cuttings, do not produce feed, 
whereas thofe which come from feeds feldom fail. The 
leaves continuing green all the year, this plant makes a 
pretty variety during the winter in the green-houfe. 
The fpecies 6, 10, 13, 14, 17, 18, 19, 21-26, 28, 
3 C > 3i, 35-fi, 57, 58, 60, 62-71, 76, 81, and 85-109, 
being natives of warm climates, chiefly of the Fait and 
Weft-Indies, are tender. When raifed from feeds, they 
mull be fown on a hot-bed in the fpring; and, when the 
C O N. 15.") 
plants are fit to remove, they muft be tranfplanted each 
into a feparate pot filled with light earth, and plunged 
into a moderate hot-bed, o'bferving to fhade them from 
the fun till they have taken new root ; then they fhould 
have a large fhare of air. admitted to them every day, 
to prevent their drawing weak, and alfo moderate wa¬ 
terings every other day. When the plants are become 
too tall for the hot-oed, they muft be drifted into larger 
pots, and placed in the bark-ftove, where if they are al¬ 
lowed room they will flower ; but they rarely produce 
feeds in England. Many of them therefore are conti¬ 
nued by cuttings. 
Convolvulus jalapa, the root of which is the true ja¬ 
lap, being a native of South America, muft be preferved 
in the bark-ftove. It may be raifed from feeds on a hot¬ 
bed, the young plants being removed into pots muft bt 
plunged into the bark-bed, and treated in the fame man¬ 
ner as. the laft-mentionecl let of plants, with this difference 
only, that as this has large, flefhy, fucculent roots, it: 
muft have but little water, efpecially in winter. The 
proper foil for the jalap is a light fandy loam, not too 
rich, and the plants fliould always remain in the bark- 
ftove. It may be alfo increafed from flips or cuttings. 
Convolvulus tricolor, or trailing bindweed, has been 
long cultivated as an ornamental plant in the borders of 
our flower-gardens, under the name of convolvulus minor. 
It is an annual plant, and is "propagated by feeds, which 
fliould be fown on the borders of the flower-garden, 
where they are defigned to remain. The ufual method 
is to put two or three feeds in each place where they are 
intended to flower, covering them half an inch with 
earth ; and when the plants come up, if the feeds all 
grow, there fhould be but two left in each place, which 
will be fufficient; the others fliould be drawn out care¬ 
fully, fo as not to difturb the roots of thofe which are 
left; after whichjhey will require no other culture but 
to keep them clean from weeds. If the feeds are fown 
in autumn, the plants will flower in May; but thofe 
which are fown in the fpring, will not flower till about 
the middle of June, and will continue flowering till th.e 
froft flops them. The feeds ripen in Auguft and' Sep¬ 
tember. The plants which bear variegated flowers 
have frequently plain flowers of both colours intermixed 
with them : thefe fliould be pulled off as foon as they 
appear, in order to continue the variegated or ftriped 
flowers. 
Soldanella or fea bindweed, growing naturally on the 
fea beach, cannot be long preferved in a garden. Of the 
numerous fpecies of Convolvulus, the following only 
will bear the open air, viz. 1, 2, 3, 4, 8, 9, 12, 44, 45, 
46, 47,48, 56 and 61. Thefe require the protection of 
a green-houfe: viz, 5, 8, 20, 32, 33, 47, 48, 50, 52 : 
fome always, and others in fevere winters only ; as 8, 
47, and 48. The reft, which have been hitherto in¬ 
troduced into culture, will not live in England through 
the winter, unlefs they are kept in a ftove. See Cis- 
sampelos, Evolvulus, Ipom^ea, P^ederia, and 
Polygonum.
