of low Growth; otherwife they may 

 be overborn by their neighbouring 

 Plants, and deftroyed. They fnould 

 have a frefli undunged Soil, and a 

 Situation not too much expofed to 

 the Sun. They flower in May ; but 

 rarely produce any Seeds in our Cli- 

 mate. 



The fourth Sort is a Native of 

 the warmer Parts of America ; fo 

 mult be preferved in Pots, and houfed 

 in Winter ; otherwife it will not live 

 in this Country. 



The fifth is a Native of the North- 

 cm Parts of America, and will live 

 in the open Air in England, pro- 

 vided it is planted in a flickered Si- 

 tuation. Thefe Plants decay to the 

 Root every Winter, and rife again 

 the following Spring.

The firft and fecond Sorts are ufed 

 in Medicine ; but, as they are very 

 rare in England, their Roots are 

 brought from the Southern Parts of 

 France, where they are very com- 

 mon, and are fold in the Shops. 

 Thefe Plants are both tolerably 

 hardy, and will endure the Cold of 

 our ordinary Winters very well, in 

 the full Ground. Thefe Roots mould 

 be plant'ed early in the Spring, be- 

 fore they begin to moot, in a warm 

 Situation ; and lhould have a frefh 

 light Soil, rather dry than moilt. 

 They mould be planted fix Inches 

 deep in the Earth, that they may 

 be lefs expofed to the Frolt ; and 

 in Summer the Drought will not 

 fo foon affect them. They will 

 moot up about two Feet high, with 

 {lender trailing Stalks, and produce 

 their Flowers in June ; and, in a 

 kind!;/ Seafon,they will perfect their 

 Seeds in this Country. It will be 

 very proper to have fome Roots of 

 each Sort in Pots, which may be 

 flickered under a Frame in very fe- 

 vere Fi ofls, fo that the Kinds may 

 be preferved, if thofe in the full 

 Ground lhould be deflroyed.
