This achievement will be unlocked on getting reward (decorative statue for Gardener) for playing Plant Creator. I was planning to add it as a hotfix, but instead it'll be implemented with update 0.2.

Everyone who will log at least once into Plant Creator before Gardener release will get the reward and achievement.

i'm closing in to getting all the other achievements. can you please fix this one as well, i'd be very happy to make 100% completion for Gardener Plant Creator. cheers!

The achievement is now hidden, will reactivate it in couple days when 0.2 is live.

just my type of a developer. <3 much appreciate taking action so fast. Gardener just got on my short wishlist.
