Which plant is technically classified as an herbaceous perennial?

Herbaceous perennials are plants that have non-woody stems and can survive year after year, typically dying back in the winter and regrowing in the spring. They often produce flowers and foliage that can be soft and are not part of a woody structure.

Philodendron Selloum, also known as Split Leaf Philodendron, fits this classification because it has a soft, herbaceous structure rather than woody stems. It is a tropical plant that thrives in warmer climates and can endure year-round without a full die-back, though it may show less growth during colder months.

In contrast, Red Maple and Pawpaw are classified as woody perennials; they have a trunk and branches that contribute to their woody structure. Lady Palm, while a palm that can grow over time and be described as perennial, is also considered a woody plant due to its palm structure. Thus, Philodendron Selloum stands out as the correct choice for an herbaceous perennial, making it the most suitable answer.
