Some of the Worlds Most Poisonous Flowers...
As beautiful as they maybe Lily of the Valley are among the most poisonous in the world. They are extremely toxic if ingested. Beautiful to look at in bridal bouquets but not something you should be decorating your cake with unless the flowers are made with gum paste.
Aconitum Taigicola(Wolf's Bane) This name comes from the fact that Europeans used to tip arrows with this flower's toxins to kill wolves that prey on their stock.
Autumn Crocus ( Naked Lady), This poisonous plant gets it's nickname from the fact that it's flowers don't bloom until the leaves have died and fallen off.
Remember these are just a few mentions of poisonous flowers in bloom and watch what you decorate. Anything that might be ingested (cake, cupcakes) at your wedding or party might just be drop dead gorgeous.
