You are surely right with the wild type of splendens. I have a "wild" strain
but it looks as it is not pure, too much color in it but stable phenotype
over more than 10 years now. Not really aggressive, rather small and slender
(depends much on nutrition), not too prolific. But a true wild one is hard
to find and even more to get at hands.
