I was just reading this in a magazine from 1966, and would love to hear your thoughts:

"Can you imagine anything more lovely to see on a cold day in winter than a window framed with morning glories? On a bright day blossoms usually close at about mid-day, but on cloudy or stormy days they will remain open all day, as if to compensate for the lack of sunshine. For this I would suggest the old favorite variety, "Heavenly Blue."

...

"Three outstanding introductions make excellent house plants. One is Red Dawn - a large, rose-colored blossom with white throat; Super Gentian Blue, which often measures 5 inches across has a light throat and is most beautiful of all; Imperialis double-flowering blue is very unusual with star-shaped blossoms of rich violet-blue. These may also be pinched into bushy pot plants or allowed to climb." The author even grows them in a terrarium "where they seem to forget their climbing habits and stay about 2 inches tall, sending out several blossoms, one at a time."

Can you REALLY grow them indoors?!?
