No way, you knew what it was?!?! And I thought I was helping hahahVery good Nik, I am impressed. It is indeed a calathea. I'm rubbish at identifying plants, i have to keep the little tags when I buy them so I can remember what they are, lol.
I wasn’t sure honestly, I can sometimes guess the family the plant comes from based on appearance. This new one you picked up I wasn’t sure as it had longer leaves than calatheas usually have.
My preferred plants are monsteras, pothos, scindapsus, and Hoyas. I believe these fall under aroids.
