mer season, and also by seeds, but the plants
which have been two or three times propagated by cuttings, seldom are
fruitful." _Miller's Gard. Dict._

It continues to flower during the whole of the summer; as it is very apt
to die off without any apparent cause, care should be taken to have a
succession of plants from seeds, if possible.

This plant, not less celebrated for its superior efficacy in destroying
worms[A], than admired for its beauty, is a native of the warmer parts
of North America; the older Botanists, and even LINNAEUS, at one
time considered it as a _honeysuckle_, but he has now made a new genus
of it, which he has named in honour of SPIGELIUS, a Botanist of
considerable note, author of the _Ifagog. in yem herbar_. published at
_Leyden_ in 1633.

"This plant is not easily propagated in England, for the roots make but
slow increase, so that the plant is not very common in the English
Gardens at present; for although it is so hardy as to endure the cold of
our ordinary winters in the open air, yet as it does not ripen seeds,
the only way of propagating it is by parting of the roots; and as these
do not make much increase by offsets, so the plants are scarce; it
delights in a moist soil, and must not be often transplanted." _Miller's
Dict._

The scarcity of this plant, even now, is a proof of the justness of Mr.
MILLER's observation; it is in fact a very shy plant, and
scarcely to be kept in this country but by frequent importation.

It flowers in June and July.
