Both varieties are best propagated 

 by offsets of the root of moderate size, 

 for if those are employed which the one 

 variety produces on the summit of its 

 stems, they seldom do more than in- 

 crease in size the first year, but are pro-

Soil and Situation. — It delights in a

 this plan, Mr. Wedgewood, of Betley, 

 recommends the earth always to be

 the leaves have attained their full size

 growth, the only attention requisite is 

 to cut down their stems occasionally in

 young shoots, and in autumn to have 

 the decayed stems and shoots cleared 

 away.

 in speaking of the onion. 



POTENTILLA. One hundred and 

 sixteen species. Hardy herbaceous, 

 except the green-house P. Vnieariloba. 

 Seed and division. Light loam. 



POTERIUM. Burnet. Six species. 

 Chiefly hj^dy herbaceous and shrubby. 

 The latter are increased by young cut-

 established. The other parts of their 

 cultivation are as for those raised from 

 seed. 



To obtain Seed some of the plants 

 must be left ungathered from, and al-
