Ontario Native Edible Fruits and Nuts
Pointing to two trees, Tom Atkinson explains that we have the makings of a golf club.
“There you have the shaft of the club; here you have the head,” he says, pointing from one tree to the other:
The shagbark hickory, with a bit of give in the wood, is ideal for the shaft.
The American persimmon, as part of the ebony family, has extremely hard wood that is suitable for whacking the ball.
Both are native North American species; and both have edible parts.
Hunting Pawpaw and Persimmon in Toronto
Our tree trek today is the result of my interest in another North American native, the pawpaw tree.
Because of my fascination with pawpaw, I tracked down Atkinson, a Toronto resident and native-plant expert, whose backyard is packed with pawpaw trees.
After I visited his yard and soaked up some pawpaw wisdom, he mentioned a fine specimen of American persimmon growing here, in Toronto.
I took the bait.
Under a Toronto Persimmon Tree
Now, in the shadow of that persimmon tree, I’m learning far more from Atkinson than persimmon trivia:
The nut of the shagbark hickory, a large native forest tree, is quite sweet.
He points to a pin oak, explaining that the leaves are often yellowish here in Toronto, where such oaks have trouble satisfying their craving for iron.
Waving toward a couple of conifers, Atkinson explains that fir cones point upwards, while Norway spruce cones point down.
There’s stickiness on the bud of American horse chestnuts, but not on their Asian counterparts.
And while the buckeye nut is normally left for squirrels, he’s heard that native North Americans prepared it for human consumption using hot rocks.
Covering more than 20 fruits, the focus is easy-to-grow fruit suited to northern gardens. Fruits include cherry-family crops, currants, cane fruit such as raspberry and blackberry, elderberry, serviceberry and saskatoon, haskap, plum family, medlar, melon, husk cherries...and more!

A Backyard Native Fruit Food Forest
In his own garden, Atkinson’s focus is on native trees and shrubs. Many of them are considered Carolinian and are, here in Toronto, at the northern limits of their range.
My own interest in native trees and shrubs has gustatory motivations, but Atkinson’s came about because of his woodworking hobby. “I thought, if I was using wood, I should be putting it back,” he explains. While no longer woodworking, he still has a garden full of native trees and shrubs.
The edible native North American fruit and nut trees in his backyard food forest include sweet crabapple, black walnut, bitternut hickory, red mulberry and beaked hazelnut. “It is really for the creatures of the area, all this bounty,” he adds. I’m taken aback by his generous attitude towards harvest-purloining wildlife, but it’s consistent with his approach of putting something back.

American Persimmon

Sitting under the American persimmon tree and looking up, I’m dismayed to find that the fruits are still green. Atkinson cautions that the fruit are astringent and bitter when unripe, so I satisfy myself with snapping pictures.
He explains that although this is a native North American species, it doesn’t usually grow wild this far north. But it grows well under cultivation.
(I found ripe, orange American persimmons a week later at Grimo Nut Nursery in Niagara, where the more temperate climate aids in ripening fruit earlier than in Toronto. They are sweet and velvety on the tongue; I’m delighted that the young persimmon tree I’ve been nurturing in my garden will have been worth the effort when it starts to fruit. And the fruit-laden trees are beautiful.)
Pawpaw
Atkinson's Toronto backyard, where he grows pawpaw trees and other native fruit trees.
Pointing to clusters of mango-like fruit, Atkinson says, “The fragrance of the pawpaw when ripe is aromatic.” He finds that the texture is like custard.
Each fruit usually contains four to eight seeds. “Like a watermelon, spit out the seeds,” Atkinson adds.
Don’t wait too long to pick it. “If it’s starting to turn brown, give it to the squirrels or raccoons,” he advises.
Pawpaws can be found growing wild on the north shore of Lake Erie into the Niagara region. Like the American persimmon, you’re not likely to find wild ones here in Toronto, but they do grow well here when planted. The large, lush leaves add a tropical feel to the garden.
Serviceberry
Serviceberry is a native edible plant well suited to growing in the city.
When it comes to native edible plants, Atkinson believes that one of the best to grow in the city is the serviceberry.
“There’s a whole bunch of them,” he explains, listing the related members of the serviceberry (Amelanchier) clan. They all have in common an edible fruit similar in size to a blueberry.
Palatability varies by species and variety. The saskatoon berry, which is also grown commercially, has consistently good fruit quality, according to Atkinson.
Serviceberry is widely planted in Toronto parks and is common in the nursery trade. They can be grown as a small tree or a bush.
In my own garden, I end up sharing my serviceberry harvest with robins if I don’t pick them quickly enough. Atkinson says that cedar waxwings like them, too.
Aside from the fruit, the serviceberry leaves turn a vibrant orange-red in the fall and the bark, smooth and grey, is showy, too.

American Hazelnut
American hazelnut is a native nut bush. It’s related to the European hazelnuts sold in grocery stores, but the nuts are smaller.
Hazelnuts send out attractive catkins in late winter, before any leaves are out.
Crabapple
“They’re a delight to look at,” agrees Atkinson as we change gears and talk about the sweet crab, a wild crabapple. “It puts on a really good show of flowers,” he says as he describes a blush of pink on white flowers in the spring, adding, “It’s as good as a flowering dogwood but in a different sort of way.” The fruit is very waxy, and very attractive, having a greenish yellow colour.
“Squirrels don’t touch it,” he exclaims. He likes the fall leaf colours, which range from yellow to burnt orange.
On the culinary side, he says the sweet crab fruit is sour, but a perfect accompaniment when roasted with a rich meat such as pork, where the tartness of the fruit cuts the richness of the meat.
Black Walnut
Atkinson speaks warmly of towering black walnut trees and of the beautiful dark wood they yield. He notes how common they are in the Niagara peninsula: “They’re almost like weeds.”
I agree with the weedy bit: My neighbour’s black walnut stops me from growing anything in the tomato family at the back of my yard. Despite its hostile actions towards my tomatoes, I have grown fond of sitting under that tree, never really considering why. “The shade under a walnut is really quite lovely,” he says, describing dappled light that results from the long leaf stalks adorned with small leaflets.
He discourages me from promoting the black walnut for edible uses because the nut meat is very difficult to extract: the shells are rock hard, requiring a hammer to crack. And the meat doesn’t come out easily like an English walnut, but has to be picked out. But by this point I’ve already decided to write about edible native plants because of their ornamental appeal.

Growing Native Fruit in Urban Areas
I thank Atkinson for the tour and email correspondence. A couple of weeks later, Atkinson emails me a photo of a broken pawpaw branch. He writes: “Steve, here is what befalls a pawpaw when in an urban setting, and there are hungry raccoons about. I do not begrudge my masked friends at all for doing what inevitably they will do when after pawpaws.”
FAQ American Persimmon
Can persimmon grow in Ontario? Can you grow persimmons in Canada?
American persimmon is reported to be hardy into Canadian hardiness zone 4, though a long growing season with summer heat is needed for fruit ripening. Best in zones zones 5b-8.
Remember: Zones are only a guideline. Sometimes you can cheat if you have a warm microclimate.
Can I grow a persimmon tree from seed?
If you grow American persimmon from seed, the main thing to remember is that they are “dioecious.” This just means that a plant can be male or female. If you grow a seed and get a male plant, you won’t get fruit from it.
Many commercial varieties produce fruit without a male.
