The 'Green Pothos 2nd Generation Gradient' refers to a type of ornamental plant, specifically a variety of Epipremnum aureum. This variety is known for its distinctive gradient color pattern, which is typically more vibrant and varied compared to the standard green pothos. It is popular for its ability to purify indoor air and is often used in home and office decor. The '2nd Generation' term may suggest a newer or improved version of the plant, possibly with better color expression or growth characteristics.
