The Potent Plant Garden, Patterned After Agatha Christie's Novels
"Poisonous plants used by some of Agatha Christie's most notorious villains have come together in a new garden at Torre Abbey in Torquay, Devon, where the crime writer spent much of her life."
"Head gardener Ali Marshall read more than 80 of Agatha Christie's novels and short stories to put together the garden. Among the plants she chose are Prunuscultivars, such as dwarf peaches and nectarines, whose fruit stones produce cyanide — the murder weapon in several novels including, of course, Sparkling Cyanide. Deadly nightshade, used by the murderer in The Caribbean Mystery is grown alongside aconite, responsible for poisoning several characters in 4.50 from Paddington."
" ' While this might sound extremely dangerous for staff and public alike we have been very careful in our choice of plants, substituting less potent garden cultivars where possible,'says Ali. 'This is a garden designed to entertain — not provide murderous opportunities!' "
"In addition to the central display, Ali has also concocted a horticultural whodunnit for visitors to solve. In the beds surrounding the poison garden she has planted a series of clues to the titles of four of Agatha Christie's short stories — a puzzle which, she says, has tested even the most avid of Christie's fans."
The Torrey Abbey Garden notes that, "In a final twist the potent plants are framed by flowerbed containing horticultural clues pointing to four of Agatha Christie's short stories."
