The Oregon Grape Holly

This particular species of broadleaf evergreen is part of a broad range of species as well as hybrids used as ornamental landscape plants. One of my ‘seedy’ friends sent me several types of seeds harvested from older arboretum collections. I love the flavor of the grape flavored fruit. It’s intense. One small fruit fills your mouth. Winter was a bit rough on the foliage on many of them but eventually I ended up with two good colonies of Dwarf Grape Holly and possibly a hybrid of it with a strong trunk and strong lateral branching. My thought is since it is related to Berberis it might contain loads of anthocyanins and be vitamin rich. In full flower, it is beautiful.

Tall robust selection.

Robust hybrid type to 5 feet.
Mahonia repens – light fruiter but durable. Shade tolerant in my hybrid oak planting.

Each of these types provides a window into a new crop with potential as an understory fruiting plant into zone 5. It is not a common ornamental anymore and deserves a wider audience as a fruit bearing plant. Selections can be rooted easily. Even the species can be grown without breeding. I once saw a fantastic fruiting type on a college campus in central Michigan. It was protected from wind from a large building. The fruit quantity was the most I have ever seen on a single shrub. Often these individual plants vary in production so heavier fruiting selections can easily be grown, selected and propagated from rooted cuttings. The soil does not have to be that acidic. Mine are growing in a ph of 6 and mulched with wood chips every three years. They do produce some stolons and these can be used to create a more robust planting or for propagation.

5 ft tall specimen surrounded by black oaks. Southwestern Michigan. Single trunk, robust plant with good fruit set. Irrigation helps with fruit quality if it’s a dry summer.

About Biologicalenrichment

I started a farm in the early 1980’s called Oikos Tree Crops. It was once a 13 acre pasture and overtime became a forest. Today I am dedicated more than ever to finding, preserving, creating and disseminating a wide variety of food plants. At my farm I explore new plants and healthy ways to raise them. I currently focus my attention on my seed repository while providing seeds and bring these new discoveries to the public at large. My farm is one of the oldest and most diverse maintained tree crop plantings in the U.S. using many plants from around the world as a form of global agroforestry applied at a local level. Every plant grown on my farm is grown from seeds. I use the tree crop philosophy as a means to expand the use of perennial, woody tree and shrub crops raised from seed without the use of chemical and high energy inputs.The two story agriculture is alive and well at Oikos Tree Crops. This blog highlights ecological enrichment as a means to improve human health and raise awareness of the possibilities of creating a healthy earth and a wealthy farmer. My story is told by describing my 50 years of farming and life experiences surrounding agriculture filled with my love of nature and my constant search for a greater diversity beyond the cultivar on a global stage.
