My purple finches started eating away at my Sedum this spring. I put a pin wheel in the plant. Keeps the birds away. Last year they did the same thing… But I didn’t realize what was doing it. The plant never bloomed, and the leaves were eaten down to the soil level.. Since we have tons of birdfeeders, and other plants, trees, and the lake all providing food and shelter, figured they can leave my Sedum alone. LOL
