Can I get the Morticulturalist achievement if I sell plants from my Zen Garden?

I'm trying to get the Morticulturalist achievement in Plants vs Zombies: Game of the Year edition on Steam and I have filled all of the slots in both my Day and Night time Zen Garden, however, I am still far from getting this achievement.

My question is this: If I sell some of the duplicate plants from these Zen Gardens to make room for the ones that I'm still missing, will I still receive the achievement?


Beska's comment is correct, this achievement has nothing to do with the Zen Garden, it is for "unlocking" all the plants to be usable in game. Many of the plants are earned by beating levels, the rest are purchased from Crazy Dave.
