Black Walnut; during Fall. Native to North America, this well-known shade tree produces prized cabinet- and furniture-making wood. It also produces pollen and plenty of fruit that’ll drive you, well, nuts when you have to clean it all up in the fall. It secretes growth-inhibiting toxins that kill nearby plants, wreaking havoc on flower beds and vegetable gardens.
