15 things about oleander for my D&D campaign

This isn't enough for a full post, but I started BSing something that I need some notes for now. 

1. Oleander was the symbol of old rebellions hundreds of years ago
2. Despite this, oleander isn't seen as a necessarily dangerous symbol, more a representation of a feeling
3. Oleander was supposedly used to kill previous political leaders
4. These stories have inspired songs
5. Oleander is used as a way of breaking up with people in Eros
6. Because of this, oleander is seen as a symbol of a broken heart as well
7. Oleander was used to kill sacrifices for the gods hundreds of years ago, though this has been covered up
8. Hence, oleander is seen by some to represent the dangerous side of religion
9. Oleander used to be used to induce hallucinations by seers hundreds of years ago (and some people still use it despite official bans)
10. Since it had this use, some see oleander as a symbol of the future
11. Oleander often grows in this world to be very tall (20 feet)
12. Thus some see it as intimidating
13. Oleander has been adopted as the symbol by the group trying to ferment chaos
14. They did this because of its power as a symbol
15. However, they are using it a bit oddly as they are rebelling to have a singular ruler as opposed to elected rulers
