Q: Have you ever seen a Mammoth sunflower stalk with more than one flower on it? This one has eleven different blooms!
A: The ‘Mammoth’ variety of sunflowers have been bred to have one big flower on top and nothing else down the stalk. But sometimes pollen from a multi-flowered sunflower gets into the sunflower field. Flowers that receive this “foreign” pollen produce seeds that make plants with multiple flowers.
It is interesting to note that even though we call the large thing on top of the stalk a “flower”, it is actually composed of hundreds of small flowers. That’s why you see so many insects there. Even the things we call sunflower “petals” are not actual flower petals but are technically ray flowers.
