No idea what the last thing's supposed to be and I've tried placing all the available options with the correct seeds.

Are you using seeds you gathered from the second biome ? The ones you gathered from the Emerald Islands won't help. If necessary, go to other nearby islands and gather more seeds.

you do use the ones from the emerald island you just look at the bottom right hand corner of the screen and it says you can switch plants

I am using the correct seeds. The second biome seeds only have 7 different options.

This might be a bug.

It is a known bug, so a fix should happen eventually.

Command to fix this bug:
Hit "f1" key
type "symbiosis healthy"
It only affect this island... it drops all eco-requirements to zero (so you'll still have 7 plant types there... but it will say you need 0, so you will be all good). Oddly enough it will say your eco is at 0% when in fact you 100% meet all requirements... but its still fixed. eco-wise, the only thing that doesnt fix is the birdhouse and deleting any dead trees.
