Hey just bought these plants on the web. Here are 2 of 15.
It was said that these need much humidity and I thought I would be a nice add to the faunarium.
It have a nice coloration and gives a small circular spike with many small rose flowers.

Hi SteOli

It looks like a type of Persicaria. Do the flowers look anything like the ones in this picture?

There are a lot of species so it might be difficult to identify accurately. They grow in a wide range of environments including alpine pastures, riverbanks and tropical grasslands.

Best wishes.
