| Paeonia mascula|
Paeonia mascula is a species of peony. It is a herbaceous perennial plant 0.5–1.5 metres tall, with leaves that are divided into three segments, and large red flowers in late spring and early summer. Native to France, Italy, Spain, Greece, Turkey, Iraq, Lebanon and Israel, this wild peony has become naturalised on two small islands in the UK.

The Wild Peony was introduced to the island of Steep Holm in the Bristol Channel, possibly by monks. 37 plants were taken to nearby Flat Holm island by Frank Harris, the farmer at the time, in the 1930s, many of which died during the World War II occupation and fortification of the island. One remaining plant was reintroduced by the Flat Holm Warden in 1982 and is protected by fencing near the path to the lighthouse. A few plants grown from seed also survive in the farmhouse garden.
Paeonia mascula flowers for just one week of the year normally in May or June in the Northern Hemisphere, and the seedpods (at one stage referred to as jester's hats develop during the summer before bursting open to scatter seeds in August or September. The flowers are hermaphrodite and pollinated by insects. The plant is self-fertile.
Steep Holm and Flat Holm are the only known places in the UK where the Wild Peony has naturalised. The likely reason for this is that the islands provide a habitat which is similar to the Mediterranean islands where the plants originate from and the relative isolation allows them some protection.
