Good Evening, 

Thank you for contacting the U of M Extension Service. 

We are volunteers who answer yard and garden questions. We generally do not answer questions from businesses. I was not familiar with Eco3 so I looked up your website. Impressive urban farm and mission. Your group might like to get the St. Louis County Extension Master Gardeners involved in your programs. Here is the link to their website: https://www.stlouiscountymn.gov/departments-a-z/extension-office/garden-farm/master-gardener-program

They are very good at yard and garden education and might advise hands on with some projects. You might be able to ask them to do a site visit and advise you on the garden beds. 

Having said that, here is a link to gardening in the shade: https://extension.umn.edu/planting-and-growing-guides/gardening-shade

Some coleus can be grown in the shade: https://extension.umn.edu/flowers/coleus

Impatiens can grow in the shade: https://extension.umn.edu/flowers/impatiens

There are many varieties of hosta and most of them thrive in the shade: https://extension.umn.edu/flowers/growing-hostas-minnesota

I am hoping the grape vines you refer to are in full sun. Otherwise you may not get any grapes: https://extension.umn.edu/fruit/growing-grapes-home-garden You might read through the detailed information about grapes. They should be heavily pruned in early spring. 

Anything you plant with the grapes will compete for nutrients and water. 

Good Luck!
