Caladiums spadix NOT forming pollen..!!!
I wanted to try my hand on pollinating Caladiums, I planted the following varieties:
Mrs. Arno Nehlring
They all sprouted and grew vigorously, pics as follows:
Candidum was the one first to sent the inflorescence:
but the next day after opening of blade of spathe, i observed that the spadix has turned brown and dry with no pollen at all..!! i assumed that it was due to very hot and dry weather, so I covered the other inflorescence of White Queen with a plastic bag to maintain humidity around the bloom, today in the morning i noticed the same thing... NO POLLEN..... the spadix is not dry but it has become brown, very similar to the first spadix....
What I am doing wrong???? how the situation can be improved?
Another question I wanted to ask is that as you can observe in the pics that my Caladiums are loosing their bright contrasting colors, Candidum and Finnie Munson started with good coloration but are becoming greener as the new growth appears, while White Queen and Mrs. Arno Nehlring are completely green with some dull pink spots and dull red ribs.... what is causing this problem?? will they remain in same dull coloration forever?
The plants receive filtered sunlight for about 3 hours in morning, afterward its bright shade all day...
