I'm a newbie gardener so I don't have too much yet... But the Tiger Lilies ( sorry if I spelt it wrong) really spruce up my home and the frost cats are good for fire bosses.
My favorites are: Couch potatoes, because i am a couch potato . alligator pear tree because the little alligators are cute bread fruit bushes because they are really easy to take care of and deadly ninja pigs
1st Place: a tie between King Parsley and Deadly Ninja Figs, because both of these plants give amber and are relatively easy to get (farming for the former, buying from NPC for the latter).
2nd Place: tie between Prickly Bear Cactus and Maelstrom Snap Dragon. PBC gives a lot of megas at elder, and MSD gives some megas too, plus sunstone.
3rd Place: Deadly Helephant Ears because they give sandstone pretty easily and reseed! ...Downside is that they're a crowns plant and aren't easy to farm some bosses for.
I know it's wierd, but gardening is my favourite part of Wiz. I've always loved the baby carrots, they are just cute! For drops the peppers, for sheer looks the Maelstrom Snap Dragon, but he seems to need pest control everyday. Love the huckleberries for the drops, also, and cuteness. My all time fav has to be White Tiger Lily! Hard to get, but really cool looking!
Alligator Pear Tree, I love how an alligator lives at the top of the tree, and it jumps out of the tree and starts circling around it when it's ready for harvest.
Moon Flower, I have a full collection of Polymorph TC thanks to it.
Evil Magma Peas, because they give Mega Snacks.
Couch Potatoes, same reason as Evil Magma Peas.
Dandelions, because my Velociraptor loves to eat them
