Lacruca perennis is called a hardy perennial, but being a 
native of the southern parts of Europe, is liable to be 
destroyed by frost, especially if not planted in a dry soil ; but 
is easily propagated by seeds. It is said to abound in a milky 
juice of a sweet taste. Grows in vineyards and in the crevices 
of rocks open to the sun, in a soil abounding in limestone, in 
Germany, Italy, and France. Flowers from June to August. 
Was cultivated by Mr, Jonn Grrarp in 1596.
