| It is correct that the plant kills the flower immediately to protect the pollenated seed. The flower pedals should fall off and over time a fattened seed pod will grow at the end of the stem. It is not fast and can spread out over months. It will vary greatly with the species.
Growing from seed is a major effort with sterile flasks and algum. It is not really a home solution. you can search the internet for a method of growing them in petrie dishes on a counter top. It may be fun to try.
Crossing a burrilla with a bossovolla Little Stars (that is the registered name of nodosa x cordata) is quite a family cross. It is hard to guess what may come out. Bossovollas take 7 years to flower so unless the burrilla adds a faster flower trait, you have a wait in store.
