Poison Oak

Poison oak, scientifically known as Toxicodendron pubescens, is a deciduous shrub easily identified by its compound leaves, each featuring three leaflets that resemble oak leaves and dainty white flowers. This plant is not edible and contains urushiol in all its parts, which causes painful, itchy blisters upon contact. It thrives in dry, sandy, and rocky areas, typically growing 2-4 feet tall but can reach up to 10 feet. Historically, Native people used poison oak for medicinal purposes, potentially treating warts, skin cancer, and as an antidote for snake bites. The sap was also used as a dye.

Maypops

            This week I discovered a very interesting plant along the gate in my back yard. Passiflora incarnata, also commonly known as maypop, passionflower, or wild apricot, is a fast growing perennial vine known for its vibrant purple flowers. The bright flower attracts butterflies and caterpillars, is a good source of vitamins and fiber, and it is even moderately resistant to deer damages! The fruit, when ripe, is yellow-green and bulblike. It is classified as a passion fruit, and its pulp is used in many jams, jellies, and even desserts! The root of the plant is also often used in herbal medications for its soothing and sleep promoting properties, treating disorders such as insomnia and anxiety. Maypops are considered mildly invasive. Their aggressive growth through tendrils and rhizomes help them to grow 20-25 feet in as little as a year!

Rattlepods

Try to say “Crotalaria Retusa” five times fast. Also known as Rattlepod, rattle weed, or rattlesnaps, this invasive annual weed is exactly what you might think. The plant is known for its bright yellow flowers and pea like pods that rattle. It is a part of the Fabaceae family, and it surpasses my expectations by thousands. It can be edible, its flowers and leaves having a sweet flavor. The roots can be used variously. They are often used to treat bloody coughs, dyspepsia, cardiac disorders, fever, diarrhea, scabies, and even impetigo! An infusion of the plant can be used in a soothing bath to treat skin infections. Despite these wonderful benefits, make sure to keep this plant out of your pastures. These weeds potentially yield toxins harmful to livestock!
