--Broad, spreading crown with a rounded shape in open areas and an umbrella-like shape in forests.
--Dark, furrowed bark that becomes increasingly textured with age.
--Single, well-formed trunk that is usually branch-free for a considerable distance from the ground.

Leaves
--Large, pinnately compound leaves, reaching up to 2 feet in length.
--Composed of 5-11 pairs of leaflets along a central axis, with a single leaflet at the tip.
--Leaflets are ovate-oblong to ovate-lanceolate with an acuminate tip and a rounded base.

Other Features
--Native to Eastern North America, found from southern Ontario to Texas and Florida.
--Prefers full sun for optimal growth and nut production.
--Shade intolerant, meaning it struggles to grow in dense shade.
--Considered a pioneer species, often found along roadsides, fields, and forest edges.
--Prized for its valuable, dark-grained wood used in furniture, gunstocks, and veneer.
--Produces edible nuts with a distinctive flavor, although the shells are harder to crack than English walnuts.

--Grows wild along streams, ravines, and areas with access to shallow water.
--Thrives in hot and dry climates, drought tolerant due to a long taproot.

Flowers and Fruit:

--Can hybridize with other walnut species like Black Walnut (Juglans nigra) where their ranges overlap.
--Provides food and habitat for wildlife like squirrels, birds, and small mammals.
--Considered a heat-tolerant and drought-resistant landscape plant in suitable regions.

Peanut, Arachis hypogaea

Some interesting facts about peanuts (Arachis hypogaea):

Technically not a nut:
Despite the name, peanuts are classified as legumes, along with peas, beans, and lentils. This is because they grow in pods underground and fix nitrogen in the soil through bacteria in their roots.

Underground trick:
Peanuts are unique legumes because their flowers develop above ground, but after fertilization, the flower stalk (peg) elongates and pushes the developing pod underground where the peanut matures. This is called geocarpy.

South American origins:
Peanuts originated in South America thousands of years ago and were cultivated by indigenous people there. Spanish explorers introduced them to Europe and Asia in the 16th century.

Powerhouse of nutrients:
Peanuts are a nutritional powerhouse, packed with protein, healthy fats, fiber, vitamins, and minerals. They are a valuable source of essential nutrients, especially for people in developing countries.

Double duty crop:
Peanuts are considered both a grain legume due to their high protein content and an oilseed crop because of their oil content. Peanut oil is a popular cooking oil around the world.

Global favorite:
China is the leading producer of peanuts worldwide, followed by India and the United States. Peanuts are a versatile food enjoyed in various forms, from peanut butter and roasted peanuts to snacks and peanut oil.

Origins and Spread:
--A cultivar (cultivated variety) of the Callery pear (Pyrus calleryana), native to China and Vietnam.
--Introduced to the US in the early 1900s and widely planted for its ornamental features.
--Considered an invasive species in many areas due to its prolific seed production and ability to outcompete native plants.

Appearance and Growth:
--Small to medium-sized tree, reaching 40-50 feet tall with a dense, oval crown.

--Fruits are small, greenish-brown, and not considered edible.

Fall Foliage

Other Considerations:
--Originally popular for its low maintenance and resistance to disease, Bradford pears have become problematic due to their weak branch structure.
--Branches are prone to splitting in heavy snow or wind, leading to safety concerns.
--Many cities and municipalities are phasing out Bradford pear plantings in favor of native species.

Alternatives:
If you're looking for a flowering tree with similar characteristics, consider native alternatives like:
