He said the charity also surveyed the area regularly and replanted it with more native bulbs in the autumn when needed.
"At this stage, the alleged offending is unexplained," prosecutor Sarah Przybylska said on Friday.Ms Przybylska also told the court that Lavrynovych was interviewed under caution after his arrest and denied arson.
The court also heard that accelerant, preliminarily deemed to be of a "slow burning nature", was used in at least one of the fires.Mr Lavrynovych was arrested at an address in Sydenham in the early hours of Tuesday and charged on Thursday.The Metropolitan Police's Counter Terror Command led the investigation because of the connections to a high-profile public figure.
In the early hours of Monday, the emergency services responded to a fire at the Kentish Town home where Sir Keir lived before becoming prime minister and moving into 10 Downing Street.Police were alerted by the London Fire Brigade to reports of a fire at the residential address at 01:35 BST.
Damage was caused to the property's entrance but nobody was hurt.
The BBC understands the property is rented to the prime minister's sister-in-law.But others are not convinced.
"You can subscribe to this scheme but you might never take off," says James Glenton, 36, from York, who is still hoping for compensation for a cancelled Wizz Air flight a year on.In July 2023, Wizz cancelled Mr Glenton's flight from Leeds Bradford Airport to Wroclaw in Poland and rebooked him on one from London Luton the next day, he says.
That meant he lost two days of his holiday, the parking he'd booked at Leeds Bradford, money spent on his hotel, and the petrol costs getting to Luton and back, he says.According to Mr Glenton, Wizz has blamed air traffic control restrictions for the cancellation so won't refund him. But he claims the airport denies this and has told him it was the airline that cancelled the flight directly.
