I definitely like them, and the radical idea has some good potential, my only issue with the sprites is that they would cluster up the screen with loads of information at all times. I was suggested by another player to have the catalog 1. start open and 2. carry a GIF of some sorts showing off the crop's ability, what do you think of that?
I think it would be still something i have to hold in my head. I would do something like "vertical vines" and "cordial corns" so something that constantly reminds you if it's ability. And the sprite should subttlely reflect the ability too. Like having a vertical shape or little hands. You could also try small icons or arrows. Look at the game Into the Breach for inspiration.
