Don’t confuse these trees with the edible chestnuts that are roasted on an open fire. All horsechestnuts have toxic seeds, flowers, and leaves. The nuts (or “conkers”) are a dangerous problem when they fall on sidewalks and, for this reason, Portland will no longer allow these trees to be planted along the streets.
