Our society is becoming increasingly tolerant of love in all of its forms, and while a monogamous marriage used to be the accepted way of doing things, polygamy is now becoming increasingly popular.
But what about polygatree?
Kate Cunningham changed her surname to Elder in 2019 when she married a tree, which resides at Rimrose Valley Country Park in Sefton, Merseyside.
And while the mum-of-two evidently takes tree-loving to another level, their relationship isn't entirely exclusive.
Kate has a boyfriend who has supported their relationship all the way, often joining her to visit her hubby and standing by as they kiss and cuddle.
However, it's unclear whether or not they've had a treesome yet.
Former teaching assistant Kate admitted that she sometimes clocks up to five visits a week, with the frequency increasing during lockdowns.
She plans to visit the tree on Boxing Day to make sure it isn’t left out of her festive celebrations.
She said: "It’s our third Christmas together now so it almost feels like tradition to get the decorations out for it.
"When I was putting them up, the tree was as attractive to me as ever in the bright December sun.
"I made the wreath from holly, ivy, pine and red winter berries which I foraged from a walk over the weekend.
"Plus I added a little spray of festive glitter."
Kate was inspired to get married to the tree by female activists in Mexico, who held similar ceremonies as a form of protest to raise awareness of illegal logging and land clearing.
For the Merseyside mum, she hoped her marriage would attract attention to a campaign to save Rimrose Valley Country Park from being transformed into a bypass by Highways England.
She said: "People still ask questions and are still unsure of my motivations behind the wedding.
"I get asked, ‘Has being married changed your life for the better?’ Yes it has!
"‘Do you love the tree?’ Yes I do!"
In August, hundreds of people gathered to protest against the plans to have a dual carriageway built through the park.
Stuart Bennett, from the Save Rimrose Valley campaign, said: "With roads and transport being the UK's biggest contributor to CO2 emissions, National Highways' plans look more out of touch with reality every passing day.
"The pandemic has shown everyone just how vital our green spaces are for our health, wellbeing and wildlife and how these need to be nurtured and cherished, not bulldozed into oblivion."
Karen Cliffe, of National Highways, said: "We recognise the strength of feeling in the area and welcome ideas for making improvements in Rimrose Valley as we continue to progress our preferred route and explore ways to minimise the impact of the scheme."
