Although Iris verna was cultivated by Philip Miller as 
long ago as 1739, and has been re-introduced from time to 
time, it has never become a familiar plant in English 
gardens. This may be due to its having been confused by 
some of the earlier botanical and horticultural writers with 
the well-known and popular Jris cristata, but in that 
species the outer perianth lobes are crested, whereas in J. 
verna they are naked. The home of J. verna is in the 
Eastern States of North America, from Pennsylvania to 
Virginia, Kentucky, and Georgia. J. cristata is figured in 
this work at t. 412. .
