Cleveland, Ohio

In season now

• Black Walnut

  Where: Scattered throughout residential areas, parks, and woodlots; common in northeast Ohio

  Green husks (now turning black) contain the nut; harvest when husk darkens and falls, crack open to extract the hard-shelled nut inside. Wear gloves—husks stain permanently.

  Look-alikes: Butternut (Juglans cinerea) has a more elongated nut and sticky husk; both are edible but black walnut is more common here.

  Caution: Toxic to horses and some plants; wear gloves and process away from garden beds.

• Pawpaw

  Where: Understory of floodplain forests and ravines along the Cuyahoga River valley and tributaries

  Custard-like fruit ripens to yellow-brown; harvest when soft to touch and easily detached from branch. Eat fresh or freeze pulp.

  Look-alikes: None dangerous; distinctive tropical appearance makes confusion unlikely.

  Caution: Fruit is fragile and ferments quickly; use within days of harvest.

• Autumn Olive

  Where: Disturbed areas, field edges, and roadsides throughout Cuyahoga County

  Red-speckled silvery berries ripen now; tart and astringent raw, excellent for jams and sauces. High in lycopene.

  Look-alikes: Silverberry (Elaeagnus commutata) is less common in Ohio and has fewer red speckles; both are edible.

  Caution: Invasive species—harvest freely to help control spread.

• Wild Grape

  Where: Climbing vines on trees and fences throughout the region; common in parks and along waterways

  Dark purple or black clusters ripen now; use for juice, jelly, or eat fresh. Leaves also edible (dolmas).

  Look-alikes: Virginia creeper (Parthenocissus quinquefolia) has five leaflets and inedible berries; grape has three leaflets and tendrils.

  Caution: Ensure positive ID; Virginia creeper berries are toxic.

• Persimmon

  Where: Scattered in open woodlands, field edges, and disturbed areas; less common than in southern Ohio but present

  Orange fruit softens and sweetens after frost; harvest when fully ripe and soft or after first hard freeze. Astringent if unripe.

  Look-alikes: None dangerous; distinctive fruit and tree form prevent confusion.

  Caution: Unripe fruit causes severe mouth puckering; wait for full ripeness.

• Acorns (White Oak)

  Where: White oak trees in parks, residential areas, and woodlots; more palatable than red oak acorns

  Nuts fall now; crack, shell, and leach in cold water (multiple changes) to remove tannins, then dry and grind into flour. Takes 1–2 weeks.

  Look-alikes: Red oak acorns are also edible but require longer leaching; white oak acorns are less bitter.

  Caution: Labor-intensive; plan ahead for processing time.
