It looks a bit like an agapanthus. I have them, and cut the old flower stalks individually with a pair of secateurs, as far down as possible each autumn, keeping the leaves as they are.
The leaves may become floppy and die over winter, but don't worry. This seems natural, and the plant recovers.
@jaynpatel87l-WbG5Q7 There are both evergreen and deciduous Agapanthus. It is a good idea to cut back the flowers to the base after flowering, for future reference. Evergreen Agapanthus are better brought inside over the winter months so a pot is a good option, unless you live in a mild part of the country.
Because it has been so much milder so far this winter, it is difficult to tell which you have but it has flowered well and seems happy by the wall. Some restriction of the roots seems to aid flowering with Agapanthus. Evergreens need just a tidy in spring, deciduous it is normal here for all the leaves to turn yellow and die back to the ground.
I have worked as a Gardener for 24 years. My latest garden is a new build garden on heavy clay.
