It is a native of Tropical America, and has sported into a number of beautiful varieties, viz.: indigo-blue, crimson, rose, white, pale-blue, striped, etc. This plant is highly ornamental when trained to a trellis, or supported on poles. Nothing is more delightful in the morning walk than the sight of these showy flowers, which were seen curiously twisted in the bud the night previous;
-"but with fair morning's touch
Rise on their stems, all open and upright."

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 last, flowers at the same time, and the seeds require the same treatment.

Of this species there are a number of splendid varieties. I. gran-diflora superba, superba alba, atro-violaaea, lilacea, and others. The flowers of all these varieties are much larger than other Morning-Glories, with flowers of the most delicate light-blue, blue with a white edge, blue with a purple center, white with pink center, and those with blue and white flowers, shaded with purplish-red.

I. violacea vera, I. rubro coerula, I. limbata elegantissama, with beautiful blue and white flowers, and many other varieties and hybrids, are splendid; eight to ten feet high.
