If you know of a source for seeds of this please let me know. I have a plant that is nearly three years old. It is more than 20 ft. tall and very healthy, but it won't produce seeds. Possibly, I need another plant of the same variety with which to cross it, so that it will make seeds. If you have a black-seeded moonflower that won't produce seeds, I can trade a cutting like the one in the picture for one of the cuttings from your Meekerii. Then, maybe we will both get plant seeds. They root very easily.
