Gardeners may have noticed some of their plants blossoming later than usual this year due to the unusually hot October weather.
Climate change will make this phenomenon much more commonplace, according to the Royal Horticultural Society.
The body claimed there are advantages to warm Indian summers, as extra warmth and light closer to winter months can make wood and buds more resistant to cold damage.
Drier soil is also a result of these conditions, which makes weed removal and planting preparation much easier.
"Plant growth happens over an extended period which can see some types bloom again," commented chief horticultural advisor for the organisation Guy Barter.
"A second flowering [can] produce a second crop of seeds," the expert remarked, adding they will already be full of resources from a good growing season.
Link, the UK cash machine network, recently claimed the hot weekend (October 1st-2nd) saw people spend more to enjoy themselves, with £577 million in cash withdrawn the preceding Friday.
