– Abundance of purple flowers during Summer and Autumn
– Plant in full sun to light shade
– Tender to frost but will tolerate light frost if planted in a protected position in the garden
– Feed monthly with a fertilizer like 3-1-6
– Water regularly in summer, never allowing the soil to dry out completely
– Growth points need to be pinched off very regularly to maintain the formal shape. This also ensures that they remain dense and lush with plenty of flowers
