I took your lead and got out the measuring tape Sandi!
I have had these nearly 3 years now and have only separated them once. It was very bushy and only separated into 4 stocky bushy little individuals. All my other Syngoniums are large and grow like weeds. This tiny one seems to be a clumper, not a viner, and the measuring tape shows the largest any leave has ever gotten; under 1 inch! Never any higher than three. I have all 4 planted in the same little garden box in different areas and hope to get them growing faster so I can make more and more!
In the Winter, I set a pole frame over the entire planter box so I can cover it without crushing everything with the cover. I then set a bulb socket with a 75 watt bulb I spray painted red under the tent in the middle and it keeps everything very comfortable! Thanks for asking.
