Commonly known as Pacific poison oak or Western Poison oak, is a woodsy vine or plant in the Anacardiaceae (sumac) family. It is allocated in western Northern America, inhabiting conifer and combined broadleaf forests, grasslands, and chaparral biomes. Optimum blooming only happens in May. Like other members of the Toxicodendron genus, T. diversilobum causes itchiness and sensitive rashes in many people after contact by touch or breathing.
Toxicodendron diversilobum is extremely varying in growth and foliage overall look. It develops as a heavy 0.5–4 m (1.6–13.1 ft) high Plant in open sunshine, a treelike grape vine 10–30 feet (3.0–9.1 m) and may be more than 100 feet (30 m) long with an 8–20 cm (3.1–7.9 in) footprint, as heavy thickets in shady areas, or any form in between It reproduces by growing rhizomes and by seeds. The plant is winter deciduous, so that after cold temperature sets in, the vines are leafless and keep only the casual group of fruits. Without leaves the stems may sometimes be recognized by periodic black spots where its milky sap may have oozed and dried. Poison oak is typical in various environments, from mesic riparian areas to xeric chaparral. It grows in sketchy and dappled mild through complete and sunshine circumstances, at heights below 5,000 legs (1,500 m). The vining type can ascend huge plant and shrub trunks into the canopy.
