Crown daisies in Norfolk
Crown daisy, Stalham, May 2007 |
This is the story of how a Mediterranean wild flower grew on RSPB property in the Norfolk Broads for three years. My first discovery, in 2007, was of least 12 crown daisy plants growing in a large greenhouse near Stalham. This was part of an organic enterprise on five fields that was itself part of the RSPB’s purchase of Sutton Fen nature reserve, completed in December 2006. |
RSPB land agent David Horsfall had organised a work party of RSPB regional office and reserves staff, and I was one of those who volunteered to help tidy up the greenhouse one evening in May 2007.
It’s highly likely that the crown daises came in with ‘contaminated’ organic seed, with the hot and dry conditions in the greenhouse and lack of sprays or weeding making ideal growing conditions. There were some old seed packets, and seed supplier Tamar Organics kindly confirmed that its seed is sourced from Italy and Israel, where you'd expect crown daises.
Plant recorder Bob Ellis kindly checked the county’s records and found that crown daisy was previously only recorded in Norfolk in 1912.
Most of the 12 plants in 2007 had the yellow and cream coloured flowers of the discolor variety of crown daisy; one was all yellow and the rest were not in flower. This is a fairly typical proportion in southern Europe, where the two-coloured form is the most usual, and this continued to be the mix for the next two years.

Some plants came home and flowered all summer in a pot in my front garden. There a few popped up again in 2008, as did many in the now more dilapidated greenhouse at Stalham. For safety reasons this was demolished in early 2009, and many crown daises grew well in the disturbed open ground that summer. A visit in August seemed to coincide with their peak, with 100 or more plants. At home, they were waning: just one appeared in my garden in 2009.

The area where the crown daisies grew at Stalham is now in arable cultivation, so that combined with the long cold winter means the odds of this Mediterranean flower appearing for a fourth year are not good.
The appearance of crown daisies in Norfolk is not linked to climate change; and for a common Mediterranean plant to grow for three years in East Anglia is of no great note in conservation terms. But it’s a natural history curiosity, now recorded here for posterity, and in the words of Flanders and Swann, “Let’s hope posterity is grateful!”
