Howdy,

After several years in the hobby, I occasionally have heard discussion of
certain groups of plants that do no prosper when in the presence of other
species.

the ones I have heard of:
cryptorynes vs Vallisneria sp.,
Val vs Saggitaria sp.

Do any of you have a more thorough list from your own experience or sources
online?

In nature, it is typical for only one species to dominate a certain niche in
a pond/lake/river. Chemical means are routinely used to get a leg up on the
competition in the rainforest in delightful irony against the stereotype of
"Mother" Nature as being a pristine, nurturing, static thing.

I've reviewed and discussed this issue in the past.
To date, there has never been ANY evidence that this occurs in natural
systems.
I've grown the above plants together without issue.
Any plant-plant interaction combinations are welcomed. I've grown many
species together over the years.

See the APD for some discussion. If you'd like to see the best
research paper on the topic, I can provide the reference.

Regards,
Tom Barr
