Beautiful photographs but glad he's interested in the primula and not the bleeding heart...

"Bleeding Heart (Dicentra formosa) contains substances known as alkaloids, which can cause tremors, loss of coordination, drooling, and in severe cases respiratory distress, seizures and possibly even death. Poisonings from this plant typically involve livestock who have grazed on large amounts. However, the potential for toxicity exists for other animal species as well, so cats and dogs should not be allowed to consume this plant."
