Morning Glory will NOT make seeds
Everyone says how they are "profilic reseeders" and how they just make too darn many. Well, I have had mine for a month or two now, and finally they are starting to bloom here and there. But, after the flowers wither, all I am left with is a dead flower, no seed or anything. Unlike my marigold which made a dozen seeds on one flower, these morning glories have indeed saddened me.
