Root tuberous. Stems from a foot to a foot and a half in 

 height, hairy, round, dusky red. Leaves alternate, except on 

 the upper part of the stem. The flowers in large clusters at 

 the extremity of the stems, of a bright orange. 



This very splendid herbaceous plant would, no doubt, be 

 found to adorn every garden if its propagation were more 

 easily effected. Unfortunately, it does not perfect its seed in 

 this country, and consequently it can be increased but slowly 

 by its root alone. 



In its native country (North America), it is found growing 

 very luxuriantly in sandy gravel, where its roots frequently 

 penetrate to the depth of three feet, and of proportionate bulk. 

 The smaller-sized roots are sometimes imported into this coun- 

 try in very good preservation when packed in sand or in moss. 

 These roots thrive very well when planted in sandy earth. 

 Upon a sandy or gravelly bank it flourishes, which renders it 

 well adapted for rock-work, where its fine orange clusters of 

 flowers may be shown to advantage. The height it generally 

 attains is about a foot and a half; and when in a soil and situa- 

 tion in which it delights, scarcely any herbaceous plant can 

 vie with it for splendour. The beauty of these flowers is 

 apparent in the months of July and August, during which 

 time, others of the same genera are in flower ; as A. amcena, 

 A. syriactti and A. incarnata, which, though not equal in 

 beauty to tuberosa, are nevertheless worthy of cultivation, and 

 will look well in the same bed contrasted with each other. 

 This was introduced in 1690.
