My plant came with a tropical plant tag but no name. It is magenta in colour and grows like a weed! Very thirsty with thick stalks. The leaves are neither round, oval, nor heart-shaped but have distinct lines from the center of leaf to the outer edge. This plant also likes a lot of light. I've never seen this plant anywhere else.
A picture would be very helpful for identification.

Junglekeeper is right. Iresine herbstii cannot easily be mistaken for anything else. It has two commonly grown forms, the red and pink-veined one like yours and a green and yellow one with occasional red blotches.
