Thank you for visiting Grimo Nut Nursery. Ernie Grimo has been breeding and propagating nuts trees for over 40 years. We continue today to find the best and hardiest selections for our northern climate. We have introduced trees from North America, Europe and parts of Asia to test here. We test all of the cultivars in our 10 acre orchard to determine the best selections for our nursery production. In this way our customers are getting the best selections available.

We list our trees as ‘seedlings’, ‘grafts’ or ‘layers’ to identify the means of production. Seedling trees are trees grown from seed. This means that they are the result of 2 parents and are not identical to either parent.  Seedling trees obtained genes from both parents making them a unique entity.

Superior trees are given names to identify them as well as clones that are produced from them. We have named a number of our selected trees. Some nurseries use the names loosely by calling their seedling trees by the parent name. This can be misleading to the unaware buyer. We always indicate our stock as ‘seedling’, ‘layer’ or ‘graft’ as part of the name or source.

To find out more about trees produced by grafting and layering, go to our FAQ.

We offer fresh nuts from our orchard and from other fresh sources too. Try the incredible taste of fresh nuts from our offerings.
