Cult, The most of the species of Quámoclit are beautiful half 
hardy annual plants. They should be reared on a hot bed; and 
about the end of May they may be planted out in an open border, 
in a warm, sheltered situation, where they will flower freely, and 
ripen their seed. Some of the more tender kinds may be grown 
in pots, in the greenhouse, during summer. The perennial her- 
baceous and shrubby kinds should be treated in the manner re- 
commended for Batàtas, p. 262,

The red-rooted sort is in general cultivation all over the warmer 
parts of Asia, and very deservedly esteemed one of the most 
palatable and nutritious roots; the white-rooted sort is more 
generally cultivated in other parts. 
The Spanish or Sweet Potatoe is a native of both Indies, and 
was cultivated by Gerarde, in 1597. He calls the roots potatus, 
potades, or potatoes, and says they are by some named skirrets 
of Peru. They flourished in his garden till winter, when they 
perished and rotted. Batatas were then sold at the exchange in 
London, and are still annually imported into England from 
Spain and Portugal. They were, in 1315, the common potatoes 
of our old English writers, the now common potatoe, Solanum 
tuberdsum, Lin., being then little known. The tubers of the 
Batatas are sweet, sapid, and nourishing. They are very com- 
monly cultivated in all tropical climates, where they eat not only 
the roots, but the young leaves and tender shoots, boiled. There 
are several varieties, differing in the size, figure, colour, and taste 
of the roots, as well as the form, hairiness, and smoothness of 
the leaves, and colour of the flowers. In warm climates this 
plant is cultivated in the same manner as we do the potatoe, 
but requires much more room, for the trailing stalks extend 4 or 
5 feet every way, sending out large tubers, 40 or 50 to a plant. 
In the national garden at Paris, the plants are raised on a hot- 
bed, and, about the middle of May, transplanted into the open 
ground, where they are earthed up, and otherwise treated like 
the potatoe. In warm seasons they produce a tolerable crop. 
M. Thouin considers it a much lighter food than the potatoe, 
and equally nourishing. In England, Miller observes, the roots 
must be planted on a hot bed in spring ; and if the plants are 
kept covered in bad weather with glasses, they will produce 
flowers, and many small tubers, from the joints; but if they 
are exposed to the open air, they seldom make much progress.
