In the shadow of the hardwood forests of North America lies a well kept treasure rarely cultivated. It is a small nut shrub called the chinquapin. Unlike any number of chestnut trees cultivated or wild, the chinquapin is mostly thought of as wildlife food. For the most part people thought the nuts were too small to fiddle with. You cannot peel them like a normal chestnut. Nonetheless they are a great wild food easy to pick or shake while crunching away skin and all. From a cultivated point of view, the plants are precocious and fruit at a young age. They prefer a lightly acidic sandy well drained soil and can grow into zone 3. At my farm they took the minus 25F at my farm several times. The chinquapin is one tough little shrub with immense staying power. Despite chestnut blight and changes in the forests over time much of it human induced, it is still here cranking out nuts like there is no tommorrow. I became super absorbed into finding this rare treasure at one point and began producing it at my farm. The little shrub that could was not particularly easy to find in commerce either in seed form or seedling. Apparently no one was fiddling with it. I had to find out why.
My first introduction to the plant came from a nursery mentor that lived near me. It was right after college and he operated a wildlife nursery out of his yard specifically for birds. He only had one shrub. As a result, no nuts. It needs cross pollination with another of its species, Castanea pumila. The cute little burs would form but with no nuts were inside. It was a joy and frustrating at the same time to see it in growth but no way to taste or propagate it.
About a decade later, I was at a chestnut farm in mid-Michigan. By now I had my farm and was producing seedling trees. They too had only one shrub and it was at the edge of the orchard. It had a few burrs but they too were mostly empty. Because the chinquapin was surrounded by a lot of chestnut trees of many kinds, there was some light cross pollination between the species and the chinquapin. But it was no chinquapin nut bonanza and no way to taste test those precious three nuts from that one plant. Eventually those went into my orchard plantings where one still survives today.


I decided to create my own seed orchard. I ordered ten plants from a chestnut nursery in Ohio who had a group of ‘pure’ non-hybrid fruiting chinquapin shrubs. Along with the hybrid plants these are the seed sources I still offer to the public. That particular seed source has been stable and fruitful despite everything around it including chestnut blight. I still have two out of ten plants. As time went on I found a seed dealer in the south that provided me with even a greater variety of subspecies found in the southeastern U.S. He was accessing wild trees which were difficult to find and even more difficult to get there at the right time to secure the harvest. Evidently the chinquapin family tree has a lot of branches throughout the U.S. Each subspecies is difficult to tell apart and in many ways are considered more of geographical variants. Some are more tree like too. The highly perishable nuts are difficult to produce a plant from because they sprout immediately after harvest. Refrigeration is not good. They rot super easy no matter how you attempt it. You have to plant them immediately. They are hypogeal in nature throwing down a root first in the fall right after the seed is fully ripened on the tree. After winter dormancy, then the top sprouts which then grows the tree. We were doing potted trees and holding them over in the polyhouses as they sprouted their roots into the pots.This was a tenuous means of growing chinquapin with a thirty percent loss but it did work better than any other method. We would mulch the pots to prevent them from drying out in the winter. This finicky nature I had experienced is the definitive power of the tree to establish in new areas. The birds carry the seeds away and every now and then drop them where they get covered by leaves or pushed into the soil by deer hooves while the root sprouts and goes deep within the soil. Even if the nut is ripped off its root and is consumed by rodents, the root is already established and is not going anywhere. As long as there is an epicotyl or sprout there is no need for the nut now. It has done its job. It produces a new plant. Once winter dormancy is set in, the epiecotyl or sprout can begin its growth in the spring after the cold period of dormancy. Its a good system. Don’t mess with it. Fit in.
Today the chinquapin has gotten new fans.I see them as non-profits, institutions and on social media. New ideas have come along with hybridization, wild forms of selected plants immune to chestnut blight, digging up and resuscitating old breeding projects of the past as well as just growing the plants as they are found in the wild with no so called improvement. Sometimes improvement is over rated. Not everything humans do to plants are beneficial in the long run. But it would be of great benefit to have additional population level plantings accessible to the public to help promote the crop. Hybrid plants may create a more precocious and delicious chinquapin with a larger nut. Nurseries are not likely going to produce it. It is too much work for them as they are scramble to stay alive. But eventually you could find it in a nursery devoted to such an endeavor and nothing else. Because the chinquapin is a native North American plant, it might get promoted on that level including the hybrids or selections. If there ever will be such a thing as a commercial crop, a shaker and a machine to separate the spiny husks and nuts as well as a means to de-skin the nut would be ideal. Like the pistachio of chestnut, chinquapin would make a good snack food. I happen to agree with a lot of people who insist the chinquapin is the best flavored chestnut in the raw state. It is quite sweet and has a very nice smooth texture. I could see where it could make a fine flour or make a great nut milk. You can also have the once in while wild snack food crunching away skin and all.
In many ways I get connected to certain plants because of all the experiences I have had with them. I tended to combine those over the years to try to grow something that others may benefit. That was my nursery despite making plants ‘commerce’. You become personally attached to those plants you grew or harvested. The last three years I made new plantings along a hillside where I lost a lot of chestnuts due to blight. I used the hybrid crosses as well as the species from the southern U.S. and put them in a single row hoping they will eventually cross pollinate each other and create full burrs of three nuts. This year a few started to flower and look robust. I planted a few potatoes around them as I mulched them with composted wood chips as if to welcome them to their new home. The deer took a few bites of foliage and added their calling cards. Chinquapin is on the move and I’m right behind it.
