I've spend about 30 hours exploring and going after exobiology recently, but I've not come across any mixed species growing together on a large field/forest on any planet, apart from bacteria being mixed with some other stuff here and there. Even the single species are quite scarse and a field or a forest of a given specimen are very rare.
In the Alpha I came across stuff like in
this footage I took in Alpha (timestamped, watch from 4:11 to 5:11). I've seen a planet in Alpha that had 3 different species mixed up in a massive field and it looked absolutely amazing. Like a proper vegetation - with a layer of grass and then a mixture of 2 other plants, all covering a massive field.
In the current version of EDO I've only ever come across fields or forests of just a single species (sometimes with bacteria mixed in, but also very rarely). It just looks poor compared to what I was finding in Alpha
ALPHA:
CURRENT (the largest I've found so far - still just 1 species

)
Did anyone see anything similar?
