It's well-known to those with green-fingers that, while the flowers are pretty, the white sap that bleeds from Frangipanis is highly poisonous. So, if you're ever tempted to pick these flowers for your wife, girlfriend, or mother, be sure that they know to be careful not to get too intimate with the sticky white sap. Mothers-in-law? Well, that's a whole other matter. :) (Only kidding, I have agreat mother-in-law, btw.)
