I was wondering about the same dilemma recently...faux flowers vs real from environment perspective...
And found the following arguments quite convincing...
However, from pure style perspective prefer real ones...

“Faux flowers all the way I used to be a florist, Since becoming more environmentally aware I can honestly say that artificial flowers are better for the environment. The amount of cellophane that the flowers are wrapped in when they arrive fills up huge bins every week. This is in addition to the CO2 emissions created in flying these flowers across the world from South America, Africa etc. Other flowers are grown in Europe in massive green houses. The artificial flowers I use now have been shipped to the UK by sea, Are in cardboard and have a life of several years. Once they have finished their use, Each stem can be de constructed to part metal (recyclable) and part plastic which amounts to about the same as a couple of biros!
Cut flowers are bad for the environment There are plenty of scholarly articles for those interested in the facts around the environmental impact of the cut flower industry.
Given that a single rose uses between 6 to 13 litres of water in the production process, Your magnificent dozen wastes a minimum of 72 litres of our precious water for, At best, 10 days use. That doesn't include the water in the vase which is recommended to be changed daily.
After brief enjoyment, It is off to land fill to produce methane which compliments the carbon emissions from the refrigeration and transport, Often from the other side of the world. Also, Add herbicides and pesticides used in production, And in some destination countries including Australia, Methyl Bromide fumigation a known carcinogen.
Cut flowers are never 'pollinated' rather they are 'decapitated'. They are often grown in temperature controlled structures which are devoid of insects, Or in the field are sprayed with pesticides.
Yes, Artificial flowers are fabric and plastic, But the same argument could be raised for our cupboards full of plastic food storage containers and non-organic fiber clothing. . . All of which will, Ironically, Be outlasted by artificial flowers with a 'lifespan' of up to 15 years.
So by all means - enjoy growing your own flowers and leave plenty of them in the garden to feed the bees and other insects. But if it is cut flowers you are purchasing, Do the environment a favor and either buy some artificial or just don't buy any at all.
Arguments ignore land use & farming practices There's a lot of nuance to this but first you have to acknowledge that growing flowers is bad for the environment full stop. They have a net impact. Most of the arguments below say they are natural and therefore better. Growing flowers takes up huge amounts of land which could be otherwise used to grow food or provide any other land use. They are also farmed with heavy uses of pesticides & fertilizer, So are no better than a food growing farm from a biodiversity point of view. Furthermore you have to take into account the transportation of huge amounts of flowers in terms of carbon footprint. In the UK many of the flowers we can buy are flown in from Africa. There's nothing about farmed flowers which is cyclical - the nutrients end up in a landfill or a compost bin in another country and there's a net carbon cost.
In terms of what's better or worse, I think that depends on how often you buy flowers. If you have to have two bouquets of fresh flowers on display in your house at all times, Then replacing those with plastic would probably be much much better for the environment than constantly buying fresh flowers.
The points about plastic flowers being difficult to recycle and dispose of are valid, But it would be interesting to see the results of a study which tried to weigh up these two options.
What about those Chemicals? To reply to the post saying that plants give us oxygen and we give plants CO2, that doesn't really work when the plants have been chopped down, does it? We can still plant all of the flowers and not of to cut them down. That would be a lot better for the environment don't you think?
