Our Story

Penny Dawson owns and runs the business along with growing two young children. She studied Landscape Management at Reading University with a year at the Royal Horticultural Society’s Garden at Wisley.

She is the daughter of Hugh and Liz Nunn who are well known for Harvington Hellebores, Roscoea, Erythronium and Trillium in the wholesale trade.

Formerly a Nunn and with the maternal family name of Twelves under threat of extinction, what more was needed to name her business…

Twelve Nunns established a nursery in Lincolnshire in 2012.  We offer plants by mail order only – we are not open to visitors.  We also grow for wholesale customers.
