I grow certain strains of Ipomoea nil and other slow growing annual species of morning glory indoors as houseplants. They do remarkably well in a sunny window, make flowers all winter long. The currently flowering morning glory I have is Ipomoea cardiophylla, which looks like a miniature Heavenly Blue Ipomoea tricolor.
Name: seaecho Phelan, Ca. (Zone 8b) There is ALWAYS room for one more p
I had a morning glory as a strictly houseplant too, and it bloomed regularly, like yours did. I keep meaning to get another one, as it was also a Heavenly Blue, and I loved the fact that you never knew when it was going to give you a bloom! They are truly delightful little plants.
They are easy to grow from a seed, seaecho. I am happy you had a good experience with the Heavenly Blue.
I am growing another one for both the variegated leaves and the small red flowers. It is Ipomoea nil, 'Beni Chidori', also known as 'Cameo Elegance'. The plants have not bloomed yet but here are views of the leaves.
