Thanks Inanimate! Yes all energy types have the same amount of options.
There'll be a total of 9 basic plants (3 different types of grass * 3 different energy auras).
Here's the current list:
◙◙◙ Basic Plants:
◘ Wild Grass:
►Wild Energies: Pixie Bush (done)
►Fairy Energies: Thistle Bush (done)
►Dark Energies: Mandrake (not done yet)
◘ Fairy Grass:
►Wild Energies: Fairy Tree (not done yet)
►Fairy Energies: Guardian Flowers (done)
►Dark Energies: xxx (not done yet)
►Wild Energies: Slime Mold (not done yet)

►Dark Energies: Death Mushrooms (done but missing the zombies)
And then I also have advanced plants like the Pixie Hive, the Fairy Fortress, the Thistle Man, the ManEater and some others.
