I have Oxalis hedysaroides in my terrarium. It's doing well but I had one stem that was dying. Pulled it out and put it in a small vase with water and it's growing roots! Is there anything particular I should be doing next?

How also can I propagate from the plant that is in the terrarium? I hear reference to seeds and bulbs for other Oxalis species but haven't found anything abotu this particular one yet.

Thanks in advance.
