'Queen of the garden'

This Potentilla was grown from a cutting of a plant that Dad loved and used to call 'Queen of the garden'. The plant had a prominent position in the garden, was huge and flowered all summer long. Dad sadly died in 2009.
When Mum moved she took the plant with her and it's still alive, but not quite back to its former glory yet.
This plant brings back memories of Dad as do so many plants in my garden.
