Too bad idea is all I have @.@
I wish I could script too then I would make tons of unique script *.*
Anyway, I always like the idea of different scripts working together so they are seen as a big system, not isolated once that is just put there for the sake of it o.O
Also would be cool if map ID can be also used to affect growth/yield rate depending on the plant. Like for example in densely tree'd forrest plants will go a tad slower (low sunlight condition) and will yield less (wild animals eating it) unless you put a scarecrow or other animal scaring stuffs o.O
And an open mountain area will make a seed grow faster because it has more sunlight o.O (though more devastating lost if hit by a storm)
Then different seeds will have different needs too *.* (Some like more water/light, while others don't)
While it may be too demanding to grow seeds, you can always just plant and leave them (but yeah, growth time and yield) Plus maybe if you grow the plant well, some might give you a rare different seed instead O.O
A berry catalog should prolly look like this (sorry for the quality, 5 mins mock up ^^;)
