Does fern have a stem?
Ferns do not have aerial stems in the manner of many other vascular plants. Instead, the leaves arise directly from an underground stem (rhizome) or a very short vertical stem at or near the soil surface. Therefore, fern stems are often very inconspicuous and the portions of ferns most often noticed are the leaves.
What is the curly part of a fern called?

Do ferns need sun?
Ferns Need Plenty of Indirect Light

Where do ferns grow best?
