Many people will tell, you have to find out first is the plant you want to grow becomes a true plant or not?
A true plant will have the same properties that the mother plant.
BUT the entrepreneur will say, take the risk and try the outcome.
May be you make an offspring that develops into the Iberico ham of the fruits which you even can give your name.
OR you just might give up your ghost after the first bite. Grow a cucumber from own seeds for example could retard to a cucumber of the begin of civilization, so bitter that you just knock over. (Very very unlikely but mother nature is always a surprise)
To be honest, as Stacie mentioned. Using a whole tomato to get a tomato plant is something for people who spread caviar in the restaurant to make the waiter slipping and crash landing.
There are a lot of YouTubers who try to invent the wheel new. Grandmother will be your personal teacher and she has thought you the best hacks.

rose into potatoes but there is NO video (as far I could find) that show a fully grown rose that came from this hack.
