I was not able to think that much even after you called it the third largest in the world, mainly because I've never seen an indoor garden. But I am totally surprised to see this indoor palm tree. This garden is not just big but massive!
And all those flowers, that giant leaf... It's so good!😊🤗
I've been to many indoor gardens, but you are right, this one is massive. Is there one near you that you could visit? I know how much you enjoy plants.
After reading your comment, I Googled it and guess what, there is no indoor garden like this not only in New Delhi but probably in the whole of India. And maybe it exists somewhere but I couldn't find any information about it even after searching with different keywords.
We have indoor plants but no indoor garden! 😅😅
I suppose it makes sense that most glass house gardening is done in cold weather counties. The two biggest conservatories are in the UK.
Maybe you are right, it must have some connection with weather and temperature. As far as I know, indoor plants grow only at a fairly balanced temperature.
