Indoor garden

I rather like the idea of succulents now that I googled indoor gardens

Forest cacti (Christmas cacti etc) are gloriously colourful and will grow easily from cuttings. I've just got back from Scotland where I admired my sister's magnificent specimen, with dozens of vivid orange blooms. I must take a cutting next time I'm there!

Streptocarpuses work very well, my grand parents had masses of them in a large trough indoors, now my mother does the same. The other plants that do very well indoors are the impatiens family, which includes the Busy Lizzie. Both have many colours and leaves to choose from.

We had a very successful terrarium, needed little attention. Unfortunately some clumsy idiot broke it -- oops.

Yes, I've also been thinking about this idea, as well.

If you could get hold of an old fish tank it would make a lovely terrarium.
Succulents are better than alpines as they are tolerant of dry heat and can have some spectacular flowers.

Try googling indoor gardens on web images, for lots of ideas. x
