Thanks for the intro to this interesting fruit. At 68, I thought there were no more surprises in temperate zone food plants for me. It is now on my list of trees I would like to plant.
And congratulations on your permaculture project!
My sister is founder and director of the Eco-Home Network. You may already know of her, because her place is in Los Angeles. Eco-Home™ is an on-going living research center that demonstrates ecological living in an urban environment. In addition to a vegetable garden, she grows more than 28 fruit and nut trees in her yard. http://www.ecohome.org/pages/index.html

I got my tree through Raintree Nursery and is just as carefree as a fruit tree can be. It is grafted onto (I think) a quince rootstock and I keep trying not to let the quince grow along with it.:) I found it a book of unusual fruits and since I only have a tiny, tiny lot I couldn't put in many trees so I tried the medlar because it stays small. I am happy with my choice. I will check out your sister's site.
