A woman who was killed by a large falling branch at Kew Gardens during a friend's three-year-old's birthday party died accidentally, a jury has found.
31 year old Erena Wilson from Hanwell, was strolling through the Royal Botanical Gardens in September 2012 when the tragedy occurred.
She died from severe multiple injuries.
It had been raining heavily in the hours leading up to the accident and tree branches are vulnerable to dropping off suddenly when they endure long dry spells followed by heavy rain.
John McLinden QC, representing Ms Wilson's family, told West London Coroner's Court said Kew Gardens failed to put up signs warning of the danger because it deemed the risk so minimal, and questioned why it had not fenced trees off.
But Patrick Blakesley, a lawyer representing Kew, said the death was a "terrible freak accident".
After just 45 minutes of deliberation, the jury returned a verdict of accidental death.
The foreman told the court the jury found "insufficient evidence to establish the cause of the branch failure".
An inquest into the death of a woman from a falling tree branch at Kew Gardens has been told it was a "fluke" that more people did not die in the same manner.
Erena Wilson, a 31 year old account executive, died while walking in the gardens with friends last year.
She was hit by a cedar branch that fell from a tree during bad weather.
John McLinden QC, counsel for Miss Wilson's family, told the inquest at West London Coroner's Court: "It was just a fluke that there was not more than one fatality or that other people did not suffer very serious injury."
He said that in the past Kew has taken steps to protect the public from falling branches, such as putting up warnings and cordoning off areas, but "these steps seem to have fallen away, for reasons that the family do not know".
The Temperate House at Kew Gardens was due to shut because of its deteriorating state. However, multi-million pound grants from the Heritage Lottery Fund, Department for Environment, Food and Rural Affairs and private donations means a five-year restoration scheme can now go ahead.
The 150 year-old Grade 1 listed building is home to the South African Cycad and the Chilean Wine Palm, the world's tallest glasshouse plant.
