Since 'Gloria Moreno' is a hybrid, the flowers of offspring from it will not be identical to the parent's flowers; Passiflora hybrids generally don't come true from seed. Now, depending on the pollen donor, you might get some blooms that look an awful lot like GM - but genetically they won't be the same. Any idea which plants are the pollen donors?
No, I can't say that I have. But with Passiflora, seeds produced from a hybrid don't result in offspring identical to the parent -- that's just the way their genes work. But since GM is the result of crossing two similar plants (mixta is one parent, and although manicata is sometimes given as the other, I suspect tripartita or tarminiana...), pollen from any of three common Tacsonias (tripartita, tarminiana, or mixta) may result in seedlings that closely resemble GM, though subtle differences are likely.
