I was wondering if it is common that when you purchase seeds from vendors, the resulting plants are non-reproductive or if this is a consequence of the particular strain that the plant is? The main reason I chose to grow morning glories is to get some seeds from them but I did not purchase the popular "heavenly blues" strain but some flying saucer ones. However, the vine is now on its last legs after a good run and some lovely flowers but I have not seen any seed pod production. I saw what may have been immature seed pods but they seem to fall off prematurely. So do you think the plants that resulted from the seeds I bought was designed to be non-reproductive or was it the strain? Or could my plant have not been in the right conditions for seed production being a central American plant growing in North West England?
