Aquilegia. Columhme. [Ranunculaceae.] Handsome 

 hardy perennials. Common garden soil ; good turfy loam 

 for the choicer sorts. Propagated by seeds, or by division. 

 The seed of the common kinds may be sown in beds thinly 

 in May ; the young plants, when strong enough, planted out 

 six inches apart every way. If they are to bloom in beds, 

 they should be nine inches apart and eighteen inches from 

 row to row. When they bloom, pull out and destroy all the 

 single and ugly ones, and, if desirable, propagate the better 

 ones. The common Columbine has sported into a variety 

 of colors ; and some of its double varieties are very beautiful.
