What are the trees called with the spikes?

Answered by Stephen Mosley

Trees with spiky seed pods are commonly found in various regions and can be identified by their distinct characteristics. These trees include the buckeye or horsechestnut (Aesculus), chestnut (Castanea), and sweet gum (Liquidambar styraciflua).

1. Buckeye/Horsechestnut (Aesculus): These trees are known for their spiky seed pods, which are commonly referred to as buckeyes. Buckeyes are native to North America and can be found in forests, parks, and residential areas. The seed pods have a rough, spiky exterior and contain one or more shiny, dark brown nuts. These nuts are often considered good luck charms and are sometimes carried in pockets or used in folklore remedies. Buckeyes are also known for their attractive clusters of white or pink flowers that bloom in the spring.

2. Chestnut (Castanea): Chestnut trees produce spiky seed pods known as chestnut burs. These burs are typically covered in sharp, needle-like spikes and contain the chestnuts within. Chestnut trees are found in both temperate and subtropical regions, and their seed pods are commonly found in forested areas or near old orchards. The chestnuts themselves are a valuable food source and are often roasted or used in various culinary dishes. However, the spiky seed pods can be painful if stepped on, so it’s best to watch out for them when walking near chestnut trees.

3. Sweet Gum (Liquidambar styraciflua): The sweet gum tree is another tree species that produces spiky seed pods. These seed pods, commonly referred to as “gumballs,” have a round shape and are covered in numerous spiky projections. They are typically green when young and turn brown as they mature. Sweet gum trees are native to North America and are known for their vibrant fall foliage, which turns shades of red, orange, and yellow. The spiky seed pods can be a nuisance as they litter the ground, and stepping on them can be painful. However, they can also be used for various crafts and decorations, making them somewhat useful.

If you come across round, spiky seed pods under a tree or still attached to the plant, it’s likely one of the aforementioned trees: buckeye/horsechestnut, chestnut, or sweet gum. Each of these trees has its unique characteristics, and encountering their spiky seed pods can be both fascinating and occasionally painful.
