I encourage goumi... but the thorny eleagnus? Very bad news here...
They are excellent when growing next to a fence... If they would stay there...
They have silvery leaves that are amazing, waving the the breeze...
And... they climb trees...And spread and spread through the woodland making passage impossible... all those thorns!
If it was possible to grow without taking over the entire county... it has positive attributes... Like fixing nitrogen in the soil... unfortunately... this one has an overall negative affect on the ecology here in the Southeast...
