I believe it is available in Canada at Port Kell's Nursery.

A friend of mine has Ambrosia. He got it from his father who grafted it to Bud 9. Not sure where/how the scionwood came from.

The fruit looks and tastes like te ambrosia apples available
sometimes sometimes at our local supermarket but is difficult to grow. My friend is cutting his tree down as
it is very prone to scab. When nearby varieties are clean, the Ambrosia is bad with scab. He does spray
Captan but never seems to get a clean crop with Ambrosia.

The fruit is too sweet for me. It does seem to bear well on Bud 9.

Its on Wagon Wheel Orchards list.

Thanks so much for the leads scott and charlie and info on your friends tree spartan. This is one that has a flavor I really do love.

I hope I'm not hijacking but I'd also like to know about Jazz. I buy a bag a week from Sam's Club.

Jazz is a club variety which means all the growers signed a contract to not distribute it; its also patented. Someday it will leak out but not yet that I know of.
