Last year I grew severy stunning morning glory plants, Heavenly Blue. I saved the seeds and planted several of them this past spring. The plants have grown very well, but not one single flower! I see the structures that should have turned into the blooms, but they never matured at all.

I didnt fertilize them. In fact I ignored them like I did last year. I figure it has something to do with having saved the seeds. Does anybody have any insight?
