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 LINNÆUS, 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.

The greater Bastard Senna with bladders. _Park. Par. 440._
The Bladder Senna, a native of the South of France and Italy, produces a profusion of bloom from June to August, when its inflated pods please from the singularity of their appearance; on these accounts, it is one of the most common flowering shrubs cultivated in gardens and plantations.
