I don't know the name of these flowers so if you can help me with the ID then please feel free. It's time to dig the archive as I don't have time to go out and shoot. I took this at the Sydney Botanical Garden weeks ago.
Agapanthus is a genus of herbaceous perennials that mostly bloom in summer. The leaves are basal and curved, linear, and up to 60 cm (24 in) long. They are arranged in two rows.
Agapanthus is commonly known as "Lily of the Nile", but it
is not a lily and all of the species are native to South Africa from
the cape to the Limpopo River. - Wikipedia
