After more than half a century, the monster cactus of Candlesby is set to reach its peak, having now reached 25ft 7ins tall.
Since smashing the greenhouse roof at the Plant Lovers Nursery in May the cactus has continued reaching for the sky.
Owners Tim and Mink Sumner-Wilson have watched astounded as the plant rose ever upwards.
This week Mink made her way her way up to the greenhouse roof to get a close-up view of the soaring specimen. But even with the aid of a ladder she was still several feet shy of the spike’s top.
The couple bought the giant agave as a tiny plant from a French nursery in the 1960s.
Nicknamed the ‘Green Giant’ after suddenly soaring to 16ft earlier this year, it has continued its upward bust and now stands at more than 25ft.
However, what goes up must come down, and with the plant now at peak height it will flower before dying.
Tim said: “It is about to flower, it is just a matter of waiting for the buds to open. They are not great big showy flowers, just 20 or so small yellow blooms.
“It has been growing since March and is now full-size. The plant dies after flowering, the cutting down is a chain saw job. It is at least 55 years old. They can live to 100, so we didn’t even know if we would see it flower because it could take so long” .
