what are the different types of hickory trees
The pecan (Carya illinoinensis) is also a type of hickory, grown commercially for its valuable nuts. Lesser-known hickories include the nutmeg hickory (Carya myristiciformis), whose nuts are edible and whose bark is smooth throughout the tree's life spans and curls as the trees age.Others, such as the scrub hickory (Carya floridana), are more localized and found exclusively in parts of central Florida.f the various types of nuts each species produces, only a few are edible by humans. Hickory trees are also grown for shade, for their hard wood, and as a habitat for birds and other small animals. All hickories reach heights of 50 to 100 feet at maturity with a spread of roughly 40 feet and live for many years.
