Good ideas. I'll give it a try. If it works I'll send another photo.

Thanks for the suggestions. I'll see what I can do.

Thank you for your message. I'm beginning to feel badly about keeping them if they're starved of light, but I really have nowhere better.

Thank you for your message. I know you are right about light, but this is the best I can manage. It is in a caravan often left unoccpied for weeks at a time, so I try to grow plants which can be left. How might I narrow the ID down to species?

This was tiny when I bought it, and it just keeps growing. I'd be grateful for an ID.

Many thanks in advance
PS Sorry if the photo is misaligned
