The firft Sort is very common in 

 moft EngUJb Gardens, where, when 

 it has been fuffered to fcatter its 

 Seeds, it will come up and flourifh 

 without any Care ; and many times 

 becomes a troublefome Weed : this 

 will thrive in the Smoke of London ; 

 fo that it is a very proper Plant to 

 adorn the City Gardens ; for it con- 

 tinues in Flower from the Beginning 

 of June until Auguf ; and fometimes 

 in cold Seafons till near Michaelmas. 

 The Flowers of this Plant do not 

 open in the Middle of the Day, 

 when the Weather is warm ; but in 

 the Evening, after the Sun is gone 

 off, they open, and continue fo un- 

 til the Sun comes on them the next 

 Day ; in cloudy Weather the Flow- 

 ers will continue open all Day, or 

 when the Plants grow in the Shade. 

 This Manner of the Flower opening 

 in the Evening, has occafioned the 

 Name of Night-primrofe ; by which 

 fome People call it. The four next- 

 mentioned are equally hardy, and 

 will grow in almoft any Soil or Si- 

 tuation. The Seeds of thefe Plants 

 may be fown in March, in an open 

 Situation ; and when the Plants 

 come up, they mould be kept clean 

 from Weeds ; and where they come 

 up too clofe, fome of them fhould 

 be pulled up, to allow room for the 

 others to grow. In this Place the 

 Plants may remain till Michaelmas. 

 when they fhould be tranfplanted 

 where they are to remain for Flow- 

 ering. Thefe Plants produce a great 

 Quantity of Seed, which, if per* 

 mitted to fcatter, will fufficiently 

 flock the Garden with Plains; but
