Silphium laciniatum aka Polarplant

Silphium laciniatum, also known as compassplant or prairie compass plant, is a tall, low-maintenance perennial that belongs to the sunflower family. It is native to North America and is found in Ontario, Canada and the eastern and central United States all the way to New Mexico. Other common names for this rosinweed include pilotweed, polarplant, gum weed, cut-leaf silphium, and turpentine plant. Its eye-catching yellow flowers attract a variety of pollinators, making it a perfect addition to any garden. Traditionally found in the American prairies, compassplant gets its name from the north-south direction in which its lobed leaves tend to point. This helped it maximize its sun and water intake in the semi-arid, sometimes harsh prairie environment. Unfortunately, its natural habitat is decreasing, making it less commonly found in the wild. Compassplant is also a rare houseplant that is easy to grow, but requires regular watering and prefers direct sunlight. It does best in well-draining soil and does not require added fertilizers if repotted every time it doubles in size.
