Sir Roderic Victor Llewellyn, 5th Baronet (born 9 October 1947), is a British baronet, garden designer, journalist, author, and television presenter. He had an eight-year relationship with Princess Margaret, Countess of Snowdon, the younger sister of Queen Elizabeth II.
Llewellyn was born in Crickhowell, Brecknockshire, the younger son of Sir Harry Llewellyn, 3rd Bt. (d. 1999), an Olympic gold medallist in show jumping, and his wife, the Hon. Christine Saumarez (d. 1998). He was educated at Shrewsbury School and then received a National Certificate in Horticulture at Merrist Wood College. In 2009, he succeeded his elder brother, Dai, to the Llewellyn baronetcy.
In 2012, Llewellyn discussed his early life at Gobion Manor and later, at Llanfair Grange, with some sadness. His parents were often away at equestrian events, and his nanny, Rebecca Jenkins, became his muse, encouraging the boy's gardening. By age 7, he was sent to Hawtreys, a boarding school.
