Your Balcony Garden

Here is another plant that is unknown to me. It was unmarked and the vendor did not know the name of it as well. They cost 4 lei each or about 1 euro. Searches on the internet have left me still puzzled.  What is known about the plant, that after testing various locations on the balcony, is that it thrives in partial shade.  If anyone knows what it is let me know.

Happy balcony gardening!
