What is your most precious, rare or irreplaceable plant?

My wife asked me the other day... "If our house was burning down, would you save a plant from the fire?"
Hesitated, but answered yes... but I had more than one plant I'd want to save! What are yours?

My most uncommon:
Avocado, 3 yrs, grown from seed (3 feet tall, three feet wide, just grew that way):

and Lychee <i>Litchi sinensis</i>, also 3 years old..

I'd also try and save my seed grown: McCurtain and eucalyptus debeuzevillei growing in one pot, as well as prickly pear cactus, and my oldest travellers palm. But that is the short list.

So many of my other precious plants are already planted outside!

What is your most uncommon, precious, rare or irreplaceable plant?

That's a tough one, I think my j-tree.
It's like who would you save "your wife or your child", I would go with the child, she weighs less. Easier to carry.
