Caucasian Wingnut Pterocarya macroptera
ABOUT
The Pterocarya macroptera, commonly known as wingnut, is a distinctive tree that can be recognized by its large, compound leaves which are feather-like in appearance and arranged in a symmetrical pattern along its branches. Each leaf is made up of several smaller, lance-shaped leaflets that are lined up side by side, giving it a somewhat frilly look. During the blooming season, it produces long, drooping clusters of flowers that have an elegant, catkin-like form. These flower clusters hang gracefully from the branches, adding a soft, textured appearance to the tree. Following the flowering period, the plant develops distinctive winged fruits that are arranged in chains, giving it the wingnut name. These fruits, cluster along the hanging stems, eventually turning brown as they mature. The bark of the tree is another point of interest, typically textured with deep furrows and a rugged appearance that adds to its overall majestic form. The wingnut's general shape is broad and spreading, capable of creating a wide canopy of foliage that provides ample shade beneath its branches.

ToxicityTo humans
Pterocarya macroptera, commonly known as Chinese wingnut, does not have a well-documented profile of toxicity in humans. There is limited available information on its potential toxic effects when ingested. However, as with many plants, it is generally advisable to avoid ingesting parts of plants unless they are known to be safe for consumption. In the absence of specific toxicity data, it is best to practice caution and keep the Chinese wingnut plant away from children who might accidentally ingest parts of it. If ingestion occurs and adverse symptoms are experienced, medical attention should be sought.
To pets
The toxicity of the Pterocarya macroptera, or Chinese wingnut, to pets such as dogs and cats is not well-established in the veterinary literature. There is no significant evidence to suggest that this specific type of plant poses a common toxic threat to pets. Nonetheless, given the general lack of toxicity information, pet owners should still be cautious and prevent pets from ingesting plants whose effects are unknown. If a pet does ingest parts of the Chinese wingnut plant and shows signs of illness or unusual behavior, it is important to contact a veterinarian as a precautionary measure.

WaterThe common name for Pterocarya macroptera is Wingnut. Wingnuts prefer consistent moisture and should be watered deeply, allowing the soil to become slightly dry between watering sessions. On average, this may translate to watering every week with approximately 1-2 gallons per watering, depending on the size of the tree and the weather conditions. It's important not to let the soil dry out completely, especially for young trees. During hot or dry spells, frequency may need to increase.
LightWingnuts thrive in full sun to partial shade conditions. The best spot for this plant would be an area where it receives at least 4-6 hours of direct sunlight daily but is protected during the hottest part of the day. Dappled sunlight can also be suitable, especially in regions with very intense sun.
TemperatureWingnuts are tolerant of a range of temperatures but grow best in areas where the average temperature is between 60°F and 80°F. They can survive temperatures as low as 20°F and as high as 100°F for short periods. However, prolonged exposure to temperatures outside of their comfort zone can be harmful.
PruningWingnuts should be pruned to maintain their shape and to remove any dead, broken, or diseased branches, which ensures the overall health of the plant. The best time to prune is in late winter or early spring before new growth starts. Pruning should be done as needed but generally once a year or once every two years.
CleaningAs needed
SoilThe Pterocarya macroptera, commonly known as the Chinese Wingnut, prefers a well-drained loam soil rich in organic matter with a pH range of 5.5 to 7.5. A good soil mix can be made using equal parts loam, peat, and sharp sand to ensure adequate drainage and fertility.
RepottingThe Chinese Wingnut is a large tree and is not typically grown in a container that would require repotting. However, if it is grown in a container, young plants should be repotted every two to three years to accommodate growth.
Humidity & MistingThe Chinese Wingnut prefers moderate to high humidity levels but is quite adaptable and can tolerate the lower humidity levels commonly found in temperate outdoor environments.
Suitable locationsIndoor
Planting Chinese Wingnuts indoors is not practical due to size.
Outdoor
Plant Chinese Wingnut in full sun, moist, well-drained soil.

Life cyclePterocarya macroptera, commonly known as the Wingnut tree, begins its life cycle with seed germination, which occurs in a suitable nurturing environment with adequate moisture and light conditions. Following germination, the seedling gradually develops into a young sapling, establishing a root system and beginning to display its characteristic compound leaves. As it grows into a mature tree, it begins to produce flowers; this species is monoecious, meaning it bears both male and female flowers on the same plant, typically emerging in the spring. After pollination, which is often facilitated by the wind, female flowers develop into winged fruits known as samaras, which are dispersed by wind and water, allowing for seed dispersal. Once mature, the Wingnut tree can reach considerable heights and will continue to reproduce annually, producing seeds that fall and have the potential to grow into new trees. Lastly, as a perennial species, Pterocarya macroptera goes through phases of dormancy during colder seasons, only to resume active growth with the return of warmer, conducive conditions.

Spring to Summer
Pterocarya macroptera, commonly known as Wingnut, is often propagated through seed. The most popular method is seed sowing, which should ideally occur in late winter or early spring. Mature seeds can be collected from the tree once they have ripened, which usually happens in the fall. The collected seeds require cold stratification for about 60-90 days at temperatures around 33-41 degrees Fahrenheit (0.5-5 degrees Celsius) to break dormancy and enhance germination rates. After stratification, seeds are sown in a well-draining soil mix about 1 inch deep and kept consistently moist. Seedlings will usually emerge when temperatures are warm enough, which can take anywhere from a few weeks to several months depending on the conditions.
