They're very tough plants...there's one pot that has been in my family for at least 70 years. It blooms twice annually for my grandmother and now my aunt (thanksgiving and easter more or less), in response to the solar cycles.

I’m resurrecting this old thread to post a couple of photos of mine this year. I thought I had lost it this summer but it spring back.

Jamie, is that one plant that produce two different colour flowers? It is very beautiful.

Thanks Lan- well it’s actually a couple of plants in a single pot
