It is reportedly a little too acidic to drink the juice by itself, but will 'supercharge' whatever you mix it into.
From one review I read, if you mix 1 ounce with 7 ounces of orange juice, you will end up with more than double the vitamin C of an 8 ounce glass of pure orange juice.
In parts of Canada, it is being treated as an invasive...it chokes out the native competitors.
Make sure to let some of the berries overwinter. The non-migratory birds will enjoy them throughout the cold months.
If you plan to plant from seed, I highly recommend
Trees&Shrubs.
Their minimum order is 1 ounce (about 2,500 seeds) for $5.70
