Beautiful colas !! Are these plants you grew ? We messed around with colchicine back in the day to create polyploid genetics, but  we didn't know what we were doin back then. Here's a good description of what happens when using it ..As microtubules function in chromosome segregation, colchicine induces polyploidy by preventing the segregation of chromosomes during meiosis that results into half of the gametes (sex cells) containing double the chromosome number than usual.
