This powerfully aggressive invasive plant has now begun producing seedpods which are maturing at a fast rate. At present there are plants still in flower, others with tiny seedpods, and still others with full-size pods. I opened one of the large ones and found 20 seeds inside. Each seed is polyembryonic, meaning it can produce 2 to 6 plants per seed. So, 20 x 2 = 40 new plants, and 20 x 6 =120 new plants. Each plant has multiple seed pods, and there are millions of these plants at FWG, so it doesn't take much figuring out to see why the plants spread so rapidly. Of course, not all seeds are viable, but these amazing plants have at least a 48% success rate in terms of seed survivability.
