PERILLA. 

 Perilla IVankin^nsis. — Purple-leaved Perilla. — An an- 

 nual, growing from tAVO to two and one-half feet high ; stems 

 branching, well covered with an ample foliage of a dark- 

 purple, almost black. Leaves petioled, opposite, oval, with 

 pointed ends, the sides dented, smooth and glossy on both 

 surfaces, sometimes slightly crisped and exhaling, when 

 rubbed, an odor like cinnamon. The flowers are at the axils 

 of the larger leaves, bilabiate, rose or pale-purple, small, 

 but very numerous and producing but little efiect. The 

 principal merit of this plant consists in the strange color 

 of the foliage, which contrasts in a remarkable manner 

 with that of most cultivated plants ; its fine habit, its ro-

 Seeds scattered on the ground in autumn will vegetate in 

 the spring, and produce an abundance of plants ; or the 

 seed may be sown in a mild hot-bed or cold frame in 

 April, and transplanted to the garden in June.

 England from South America in 1831. Tliis now very 

 . common plant was at that time considered a valuable ac- 

 quisition to the floAver-garden. We now wonder how a 

 flower-garden could be formed without the Petunia, the 

 Portulaca, the Verbena, Druraraond's Phlox, and a host 

 of other ornamental plants now considered indispensible, 

 which have been introduced since that time. The fine 

 rosy-purple flowers of this species make a grand display 

 through all the summer months, and in September and Oc-
