History Lycium harharum, which is frequently seen covering 



the porches of cottages, and garden arbours, and is 

 commonly known as Tea-tree, was introduced from North Africa in 

 1696. It is so hardy here that any fragment inserted in the soil will 

 readily root ; it may in consequence be seen occasionally forming part 

 of a hedge. It was at one time recommended as a substitute for Tea. 

 L. afrmn also came from North Africa in 1712, and L. europoeum from 

 Southern Europe in 1730.

 method may be followed either in autumn or spring. They are excellent 

 plants for gardens close to the sea, where they are frequently planted
