Our cherished crambe cordifolia is ailing this Spring and we can"t figure out why. She's been happy, huge, and healthy for three years but this year she's grown to only about a quarter of her regular size, with yellowing leaves, and small, wilted flower stalks. Nothing had changed in her environment as far as we know - watering schedule (drip irrigation), soil/mulch, fertilizing, etc, it's all as its always been. Local nurseries have polar opposite opinions on what's happening to her and what she needs. Does anyone have experience growing cc and can advise? Many thanks, James
