Saturday Quiz – Poisonous Pairs – The Answers!

Title Photo by By Benny Trapp - Own work, CC BY 3.0,

Dear Readers, what a tightly-fought quiz this was! First up, welcome and well done to Oneforestfragment, who got 9/10 for which plant was poisonous and which one wasn’t. Then, for those who also named the plants, we have Mike at Alittlebitoutoffocus with 24.5 out of 30, Claire with 25/30, FEARN with 27 out of 30 and Fran and Bobby Freelove the winners this week with 28 out of 30, so well done everyone! What I’ve done is to give one point for identifying the photo of the  poisonous plant, and then one point for identifying each of the plants. In two cases it turns out that both plants are poisonous to some extent or another, so for fairness I’ve given you a mark which ever one you chose.
