Nymphoides sp. Taiwan
Super cool plant that I have been growing and ok hoarding in my greenhouse. This variant of the species originates from southern Taiwan. The rosette plant can become 6-10” tall and 4-6” wide.
What you are getting from me had a good 6-8 leaves on it and has been grown in good soil based substrate.
The plant is fast-growing and easy to care for under varying conditions, but for optimal growth it requires a lot of nourishment at its roots. While this is not a beginner plant, I would not be afraid of if if you have been keeping plants for awhile.
