Organ failure: Mr Greenaway (left) is thought to have been poisoned by an aconitum on an estate owned by Christopher Ogilvie Thompson and his wife Katherine (right)
A gardener was killed after apparently brushing against a super-poisonous plant while working on a £4 million country estate.
Nathan Greenaway is thought to have touched the toxic flower aconitum, also known as Devil's helmet and Monkshood, as he tended the garden at Millcourt House, Hampshire.
The experienced 33 year-old groundsman was one of several staff employed at Millcourt House, owned by former venture capitalist Christopher Ogilvie Thompson and his wife Katherine.
An pre-inquest hearing was told that Mr Greenaway died in hospital from multiple organ failure.
After mysteriously falling ill, the gardener was rushed to hospital but despite frantic analysis of his blood, doctors were unable to work out what was wrong with him and he died of multiple organ failure more than five days later.
The coroner heard that it was only after his devastated father, Richard Greenaway, carried out hours of tireless research in an effort to find out what happened, that the link with the aconitum plant became apparent.
Tragic: Mr Greenaway, 33, from Aldershot, was an experienced gardener North Hampshire coroner Andrew Bradley heard a report from histopathologist Asmat Mustajab, who concluded it was "more likely than not" that Mr Greenaway died after coming into contact with the deadly purple flowering plant.
He was employed by South African-born Mr Ogilvie Thompson and his wife to maintain the manicured gardens of their sprawling estate in exclusive Upper Froyle near Alton, Hampshire.
The inquest was toild that the gardener was thought to have handled the highly-toxic plant, which is a member of the buttercup family of ranunculaceae, while working on the estate. He died in hospital on September 7 this year.
Poisioning from the aconitum plant can occur if it is ingested or handled without gloves. In severe cases the poisoning causes heart arrhythmia and paralysis of the heart and respiratory centre after symptoms including vomiting, dizziness and diarrhoea.
Millionaire Mr Ogilvie Thompson is a consultant for high-end technology companies and formerly worked as venture manager for operations at Element Six Ventures, a fund focusing on early and growth phase investments in material science companies.

The attractive plant has also been responsible for several high-profile human deaths, including that of Canadian actor Andre Noble, who died on a camping trip in 2004 after accidentally consuming the plant.
In 2009 Brit Lakhvir Singh, dubbed the 'Curry Killer', poisoned her lover Lakhvinder Cheema with a curry dish laced with Indian aconite, from the same plant family.
Barrister Tim Sharpe, representing the Ogilvie Thompsons, told the pre-inquest hearing in Basingstoke, Hants., that an expert on plant toxicology was needed to establish whether or not coming into contact with aconitum was the definitive reason for Mr Greenaway's death.
Coroner Mr Bradley said that, while blood samples taken after Mr Greenaway's death were still available for analysis, the sample taken at the time of his admission had since been destroyed.
Dr Maggie Bloom, representing the family of Mr Greenaway, who lived in nearby Aldershot with his wife, said: "There's even a note in the medical records where it says all samples are to be retained."

The gardener's widow, Tegan (corr), and his parents, Richard and Marian, listened intently to the proceedings with other members of the family.
Addressing them at the end of the hearing, Mr Bradley said: "I'm sorry that we are not progressing this today. I am acutely aware of the difficulties that go with these cases and we will achieve what we can."
Mr and Mrs Ogilvie Thompson's Grade II-listed Georgian house lies at the heart of a sprawling complex of outbuildings and staff cottages at the end of a long gravel drive, next to the River Wey.
At the back there is a veranda with seating room for at least a dozen guests, overlooking a perfectly manicured square lawn featuring two black sculptures of sheep.
A gleaming blue BMW and a red Mini were parked on the driveway to the palatial residence today/yesterday (Thurs).
Other gardeners employed by the Ogilvie Thompsons tended a vast vegetable patch to one side of the house, which also has several outhouses for its army of staff, a chauffeur's cottage and even its own cavernous barn complete with ornate weather vane.
A member of staff, who asked not to be named, described Mr Greenaway as "a really nice guy who was really good to work with."
Answering the door under an elaborate, colonnaded porch, today/yesterday (Thurs) Mrs Ogilvie Thompson said the couple did not wish to comment on the inquest or the circumstances leading to their gardener's death.
