My neighbour gave me some of these to stop our hill erosion and it's working quite nicely! I took some cuttings and planted them up with some lemon grass to form a border around a small patio downstairs but can't remember what they are called. They're waxy and the leaves are thick. A little white sap comes out when they're cut at the stem. The flowers are a redish tone but I don't remember the shape as it wasn't in bloom when I took this. Can someone ID it for me please and thank you!
