250 BRECK’S NEW BOOK OF FLOWERS. 
tiful perennial from Virginia, with large white flowers, 
with purple centre; in bloom from June to September. 
It is a climbing plant, and grows about twelve feet high. 
It has large tuberous fleshy roots, similar to the Sweet 
Potato. There is a variety with double flowers, but it is 
not so handsome as the single. 
I. lacunésa.— Starry Morning-Glory.—A handsome 
North American species, with delicate blue flowers, ap- 
pearing from July to September; grows ten feet high. 
There is a variety with white flowers. The seed should 
be scalded before sowing, or not be put into the ground 
until it is thoroughly warmed. 
I. Nil.—Indigo Morning-Glory.—This highly beautiful 
species which is found growing wild in the Southern 
States, but it is supposed to have been introduced from 
Tropical America. It attains the same height as the lagt, 
flowers at the same time, and the seeds require the same 
treatment. The flowers are usually of a clear blue color, 
and its name is said to be from Anil, one of the names 
for the Indigo-plant. 
I. hederacea.—Ivy-leaved Morning-Glory. — Of this 
species there are a number of splendid varieties. JZ. gran- 
diflora superba, superba alba, atro-violacea, lilacea, and 
others. he flowers of all these varieties are much larger 
than other Morning-Glories, with flowers of the most del- 
icate light-blue, blue with a white edge, blue with a pur- 
ple center, white with pink center, and those with blue 
and white flowers, shaded with purplish-red. It must be 
treated in the same way as LZ. lacunosa, to produce satis- 
factory effects; but, when well established, they will af- 
ford a fund of pleasure through the season. J. violacea 
vera, I. rubro cerula, I. limbata elegantissama, with beau- 
tiful blue and white flowers, and many other varieties and 
hybrids, are splendid; eight to ten feet high.
