I just updated the Gardening Guide with where to find Tomato. It is in Oasis Springs up the road from Slipshod Mesquite (the home that looks like a trailer) in a planter box. There is a screenshot to help locate it. I have a feeling these plants are not random at all and it is going to be very tedious to find all the rares.



Edit: Having looked all over the world, I realize the way to get the rest of the rares is likely to combine this with that.. I'm going to have to set up some method to test each possible combination and figure out what is unlocked. I want the Gardening guide to be good, so this is going to take a while..
