Beautiful, healthy plant
Small on arrival but soon thrive - even in very chalky soil like mine. Bees love the beautiful pink/purple flowers. Mine are in their 2nd year and around 1ft tall, covering around 2ft sq. I also now have a bonus baby plant! Easy to maintain. My tips: Can wilt slightly in particularly hot weather but soon recovers. I wouldn't plant in full sun. It sulks (big time!) if you need to move it so plan well initially.
