A couple of judges that I know well out of the NE center are both curators of tropical plants. One is at the Bronx Botanical Garden while the other is at the Brooklyn Botanical Garden.
I remember them saying 2 things about this type of plant. They seem to bloom when they are good and ready and two, they applied a lot of fertilizer to them. All of the fertilizer came directly from the Prospect Park Zoo in Brooklyn or the Bronx Zoo across the street in the lower Bronx.
And I mean lots of fertilizer!! The richer and stinkier the better.
That's all I got!!
I don't remember which animals but likely bison, giraffe, water Buffalo, elk, deer, who knows!
I know that both places used to sell "Zoo Doo"! Maybe they still do.
