I don't think I have any extra lotus yet, I'm having problems with mine :'( However, this is what I do have:
Corkscrew Rush
Zebra Rush
Imperial Taro
Violet Stem Taro
Dwarf Umbrella Palm
Blue Pickerel
Floating Hearts (I'd just have to make sure I have enough to share, I should)
I'm sure I'm forgetting something. If I come up with anything else, I'll let you know!
*Edit* I was forgetting Arrowhead and Lizard Tail. I also have floaters, but this late in the season, I'm sure you don't want those.
