Quoted By:
After you have removed the bulbils, a good sign is when the flowers start to turn purple, like pic related. I've not messed with cultivars where the flowers don't turn purple, but according to others, flowers that don't turn purple are far less likely to be fertile. As you can see in pic related, they are just starting to turn purple, and I removed the bulbils 4 or so days ago. They were white.
