My friend paid a big sum and imported seeds of an exotic flower. She was a success. But she threw away surplus plants that she got from the seeds. She refused to share. She said that if she shared then the flower would no longer be exotic or rare. What would you do in those circumstances?
I think the reasoning of your friend is very shallow, because her reasons don't sound reasonable, am very sorry to say that. The truth is that if I were to be in that circumstance, knowing what her thinking is like, I would just let her be, it's her money anyway.
Seeds might be patented and she is not permitted to on sell or even propergate etc Selling/giving/even just throwing away without destroying may leave her open to legal action! or She could be a selfish bitch! Many farmers are not permitted to sew seed from a patented crop and must buy new seed to sew every time!
That doesn't make much sense: one or two more flowers shared with you or someone else wouldn't have made them less rare. I mean, it's not like anybody is going to start a business of exotic plants? Anyway there is not much you can do in this situation, the flowers are hers, she can whatever she wants... you can't really force someone to do something they don't want to.
The latter seems more likely She got a lot of joy when whoever visited got amazed at her rare collection. She perhaps wantedto have that position and therefore did not want to make that flower common.
I think scarcity mindset among people can't be helped. They do it to feel exclusive. And in such case the best option you can do in such case is find out the exotic plants yourself and give it away. Not making it exclusive seems to be the only way to combat this sort of situation. I have seen people making gardens this way and then distributing the plants to others. That is one good way to solve this issue. Not many people will like you for this action but you end up helping future generations to avoid this sort of mindset.
I found it odd too. Giving is a joy and not all are blessed with this quality. Sooner or later that exotic flower will no longer stay that way as if not this person someone else will propagate it.
