A yellow one, in fact.
According to Wikipedia,
Allamanda cathartica is also notable for its medicinal properties: all parts of the plant contain allamandin, a toxic iridoid lactone. The leaves, roots and flowers may be used in the preparation of a powerful cathartic (hence the name); the milky sap is also known to possess antibacterial and possibly anticancer properties. Gardeners exposed to the sap will develop rashes, itch, and blisters.
Wooh, I didn’t know I have therapeutic properties and is poisonous at the same time. 😀
Nevertheless, thank you JayWalk for the cute effort! 🙂
I am a Thiangllamanda!
