shifted finally for blooming in pots. The new double varie-

 grown, they sow themselves yearly.

POTENTILLA. Cinquefoil. [Rosaceae.] Hardy peren- 

 nials, now becoming popular, and comprising some fine 

 garden varieties, as well as very handsome species. They 

 grow best in loamy soil, rich in vegetable matter, but not too 

 full of dung. The roots should be taken up early in au- 

 tumn, and parted ; each crown or heart, with root attached, 

 forming a plant : these may be either planted in a bed, to 

 become established, or put out at once in the borders or the 

 flowering-beds. A bed filled with the varieties of Potentilla 

 has a very fine effect during the chief of the summer 

 months. Seedlings should be raised from the best varie- 

 ties, to obtain distinct kinds.
