What is a word that means "the state of having an organic nature"?

Consider the following paragraph:

Gramsci believed that languages created in a laboratory (i.e. Esperanto) do not develop organically in the mind of a nation and its individuals. The imposition of externally derived rules and language that have no 'organic nature' (Italian: organicità) was tantamount to putting the mind in a straitjacket.

What word could be substituted for 'organic nature'?

organicity & organicness seem like possibilities, but I've never come across either of them.

I wanted to say something about the meaning, since I speak Italian natively.

Organicità in Italian is an "ordered, harmonious and rational connection among the various parts of a whole". (It makes sense in English, right?)

So, Organico means "to be well-balanced, harmonious and ordered in all its parts".

The phrase Sam suggested is ok, although it describes the situation from a slightly different point of view. I looked up Organicity and I only found it on the OED. So it exists in English, or better, it "existed" because, looking at the Ngram Viwer, I suppose it's not really that used lately.

I would rephrase the whole sentence to something like:

The imposition of externally derived rules and language that didn't evolve organically was tantamount to putting the mind in a straitjacket.
