My string of hearts is flowering and I’m trying to manually pollinate it. Any advice? The flowers are tubular with an enlarged base and petals that sort of block off the entrance so I tried to pollinate them by just removing the Corolla of two flowers and putting what I assume is the pollen sacs from one of them on to (what I assume is) the stigma of the other. I’ve found some pretty vaguely labeled images of the flowers’ structures and I have some meager biology/botany background that I’m relying on. The natural pollination of string of hearts is extremely interesting so I recommend looking it up to anyone interested; the only issue is that it’s virtually impossible to replicate it accurately at home, especially with the resources available to me.
