Yesterday, I noticed a funny little "ball" in the crown of my D. madagascariensis plant. Today, after it has grown a bit, it is clearly a flower stalk emerging. I am very excited since this is the first flower it has ever made and I've only had it since January. I was wondering if there are any things that I should do? Like, do the flowers self-pollinate? Or do I have to pollinate it by myself? And, how tall will the stalk get? Soon some seed should hopefully become available for anyone who wants some.
