PlantFiles: Japanese Morning Glory
Ipomoea 'Maisugata'

Grew them and loved them. Started them early, grew quickly and when they finally bloomed, what an awesome sight! Will grow lots more of these next year if I can find seeds. Mine didn't produce any before it died. Kept in huge pot all late spring and summer 'til labor day.
Beautiful! Very Eye-Catching!

The Morning Glory shown here is one of the true interspecific hybrids created by the esteemed Dr.Yoshiaki Yoneda as one of the yojiro (white rayed) types...The Mt.Fuji series being another one of the yojiro hybrids.
The flower sepals as shown here, which are very elongated(!),but still triangulated in shape, look very characteristic of Ipomoea nil,but in actual fact,this plant is a true interspecific hybrid of Ipomoea nil and Ipomoea purpurea.

So far. this has been one of the toughest Japanese Morning glories I've grown with the blooms lasting well into the afternoon in the shade. Very beautiful deep purple color with white spokes, the blooms are about 4" across, some a bit larger. The translation I got for this name is as follows:

Maisugata...a dancing posture
Mai means dancing, sugata means a posture, pose, figure, form. So, one's dancing posture.

I planted seeds I got from Japan and had 100% germination on them - fast growers and fast bloomers. Seeds DO NOT need to be soaked before planting.

These are one of my favorite Japanese Morning glories - not as tender as some of the others and excellent color!
