the growing season and germinate readily.» Very early spring 
seedlings may be ready to bloom before frost, and then resume 
blooming the following spring, equipped with highly dissected 
leaves. Later seedlings will not bloom until the following spring,

beginning with somewhat less dissected leaves. Fall seedlings 
frequently seem to start blooming the next spring with almost 
entire leaves. In other words, the winter rest period permits 
many young plants to bloom which would otherwise require a 
greater degree of maturity or senescence. 
The same relations hold true of rejuvenated plants. Secondary 
rosettes which have started early begin) blooming the following
