Any Ficus or Schefflera will get large and love full sun.

Fiddle leaf

Or monstera is very trendy also. Just be careful between borsigiana and deliciosa. Some sell borsigiana as

Thanks guys, but when I google about all these plants it says everywhere that they prefer INDIRECT light. How come?

Because they are woodland or forest plants by nature....direct all day sunlight may be too strong for them.

How big is big? One can get some serious height on Yucca elephantipes, various Dracaena, cacti, cordyline, some palms, olive tree.

1.5-2meters high

Let me tell about where I live: there's are almost no full sun days during the winter.

In the autumn/spring there will be some days a month of sunny or half sunny days (unpredictable).

In the summer there will be some period of full sunny days. maybe like 10-15 days per month.

Oh my god, where is that place?

Belgium

All north Europe actually

So does this glassed-in veranda actually receive direct sun? Does it have a glass roof as well?

It sounds like there is a lack of 'direct' sunlight, in which case the suggestions made previously upthread - ficus, schefflera, monstera - would work perfectly well.

No, no glass roof.

There can be a day or two or three with direct sun, yes.

Is it heated in winter?

Have you checked instagram? Plantfluencers would be able to give you lots of ideas

Ficus, especially Benjamina is a FULL DIRECT SUN loving plant. It will will turn into a huge tree.

Not indriect light. Full sun.

Floral, yes, of course. it's always warm (21c degrees at least) in the house

It is triple glazing actually.

Ok, i will put some ficuses and see how it goes :)

Thanks everyone!

Ok. I imagined this verandah as a glassed in balcony, not as part of the house. How about a picture so we all understand what you have?
