This is a vintage Sadler, England teapot in the Indian Tree or Indian Peony pattern from the 1960s.

The 6 to 8 cup ironstone tea pot measures 6.5 inches high by 10 inches long by 6 in diameter and is in excellent used vintage condition with no chips, cracks, crazing or wear and is as if it has never been used.

Absolutely beautiful! Let's party! Tea that is!
