Ipomea (Morning glory)
I saved some seed of Ipomea caerulea (the sky-blue one)about 6 months ago and sowed it in the garden about 6 weeks ago - after the first Spring rain. We have a subropical climate. I didn't want to do it earlier as the "winter" is very dry. None has germinated. Morning glory grows like a weed here generally. Is it because I kept the seed too long?
