Impressive! I know the weird aspect of this. When moving an office, we had these huge pots full of soil and Semiramis stuff. Like, too heavy for one person to carry. Devoid of plants. We thought, put those into the dark storage room downstairs and out of the way, once we unpacked the boxes take them out and re-use the soil. Weeks later when we got to it, we entered the storage room, turned on the light and saw frigging chest-height plants had grown from nowhere and were blooming. Fascinating.

@carstenraddatz That's amazing. That must have been quite a surprise! I am genuinely fascinated by the way this plant has just suddenly produced an unexpected bit that just keeps growing and growing and growing. So fast that I'm surprised I haven't caught it in the act.
