Fatsia japonica springs to mind...

What does your text tell you, Mb95? There is a specific name for that sort of plant, and if you search that name, you will get dozens of examples. Note that this type is dependent on climate: in my area, 90% of the non-coniferous plant palette is evergreen, but it's a much smaller percentage in cold areas, like the UK.

Just do an internet search for 'large leaf evergreen plants'. You'll be presented with lots to choose from.

The lists endless ?

But two you will be familiar with are holly and ivy.

what is your project on exactly and is this for your degree? the subject might help us suggest a suitable range of plants for you.

welcome to GoY too?

Come to think of it neither of my suggestions have what you'd call "big" leaves but certainly bigger than pine needles...

OK, I'll relent. The proper horticultural term is "broad leaf evergreen", meaning any plant which keeps its leaves year round, and isn't a conifer. The name applies no matter how "broad" the leaves are, whether a tiny leaved Boxwood, or a big leaved Magnolia grandiflora. Now, if Mb95's project includes finding evergreens with large leaves, he could check the official descriptions of what he (or she) finds by searching "broad leaf evergreen", though I suspect Fatsia and Magnolia top the list for the UK.

I am a third year student studying Forensic science and my idea is to do with fingerprints on plants as there isn't a lot of information out on the internet about it. I have spoken to my professor and we both came up with the idea of picking out a plant that is an evergreen plant. But I need it to be with quite big leaves and something that is low on maintenance as I would possibly buy it and then keep it in the lab...

I am researching the fatsia japonica. I am just thinking about the size of the leaf as they can grow quite big..

thank you to all of you for your help, I really do appreciate it!

Maybe one of the Laurels, then? Though they will need higher light levels than the Fatsia. If a plant that will survive winters outdoors in the UK isn't a prime consideration, then most houseplants would fit the bill, probably Ficus binnendijkii 'Amstel King' would be the easiest to grow in the lab.

If the leaves would be big enough a peace lily would be undemanding - very tolerant and happy with lower light than many. Likes a north facing window.

At the other end of the scale the Swiss cheese plant, Monstera deliciosa has very big leaves and takes neglect in its stride. It gets huge eventually but for the several years your study would probably take it would be OK - you can always cut the top off if it gets too big. And the you can donate it to the Uni as a plant for the atrium or somewhere...try advertising for one on Freecycle!

You can grow Fatsia japonica as a houseplant, its relatively easy - it needs a cool, well ventilated and bright (daylight) sunless position, so average warmth, cooler in winter, avoid temperatures above 21 deg C. Water regularly spring through to autumn, reduce watering in winter, a little winter sun does no harm. Water when the surface of the compost feels just dry to the touch, and water thoroughly, tipping away any water left in an outer tray or pot 30 minutes after watering. They grow quite fast, so buying a smaller plant isn't a bad idea...
