I am new to gardening and in particular indoor plants, is this the
appropriate group for this? Could I post some (small) pictures to this
group for advice?

Latest highlight is that I have brought a Wollemi Pine and have it in my
study near a window, I presume this will be sufficient.

I have some Peace Lillies which I just repotted, they are going nuts.

I also have read that indoor plants are good at improving indoor air
quality, any thoughts on this?
