Autumn Olive Elaeagnus umbellata

Even though I know autumn olive is invasive, I bought one 2 years ago for twenty dollars.   I have a collection of different rare and unusual fruit plants and autumn olive makes almost the best juice of all the many kinds I have been making for the last several years.  I believe it was 'Cardinal' which sounded like the biggest fruit, best taste, or most prolific--however I believe that it was the same cultivar that we used to sell at the nursery and that the conservation department used to give out to people.  I spent a couple hours today helping my boss, Elmer pulling them out where they are escaping into the woods- growing from seeds spread by birds.
