It hasn't been added yet. This update added icons only for Health Nut and Hippity Hop Gargantuar.

Also, the fact that there are classes that have less than 10 new cards (and Mega Grow doesn't even have a second legendary as you said) makes me believe that a few more cards need to be made Set 2 (maybe something like Genetic Amplification or Photosynthesizer, they fit the theme).
