Ernest Markham Clematis
Magenta-red flowers with brown anthers that bloom late when others have faded. A solid, underappreciated red clematis.
Dangerous to cats
Toxic to cats and dogs. The bitter taste usually stops them before they eat much, so serious cases are uncommon.
Handle with care
The sap irritates skin and can raise a rash or blisters on people who react to it. Wear gloves when pruning, and wash your hands afterwards.
