2022: A buttload from seed. Put most of them in the rocks and stuck a few in the GH around one of the barrels.
2021: 4 tiny plants from seed. Very slow to get any size to them so far. Planted - E of water middle by pink crawler, in front of the water in the flat area, behind the water, not sure.
I don't actually expect these to make it through the winter. It's rare for me.
