You have some challenges wanting to grow your Pink Elephant from seed. It's a hybrid and won't come true from seed, meaning the seedlings may not look like the parent. Not all hybrids set viable seed, and with those that do may not set seed at all times of the year, seed pods with ripe mature seed may not form from all flowers, only flowers that form under certain weather conditions.

Same is true of your Fireball, also a hybrid and both are patented plants.
