Is this an Andreanum? You have to let the berries develop. They turn into little sacs like pomegranate seeds. When you can run your fingers over them and they just fall off, they are ready to be popped and sown. This takes an indeterminate amount of time depending on the species of Anthurium. for example, anything with clarinervium ancestry can take 8 months to over a year to reach ripeness. Just monitor it right now, and keep us posted!
