A plant in Dorset has grown "monster" leaves spanning 3.3m (11ft).
The foliage of the Gunnera Manicata grown at Abbotsbury Gardens, near Weymouth, is almost a metre longer than its average diameter of 2.5m (8ft).
Head gardener Stephen Griffith said: "This damp cool summer has produced some enormous leaves measuring 3.3m across and could be a record breaker."
The plants are commonly known as Giant Rhubarb and are native to the Serra do Mar mountains of Brazil.
The Gunnera Manicata at the subtropical gardens is 30-years-old and Mr Griffith said they got bigger with age.
A Royal Horticultural Society spokeswoman measured RHS Wisley's own Manicata leaves and said they were between 2.1 and 2.2m (6.8 and 7.2 ft).
She described Abbotsbury's leaf as "something of a monster".
The sheltered gardens have their own a micro-climate and were established in 1765.
