Are ferns considered simple or compound?
In nearly all extant ferns, leaves constitute the dominant organs of the plant. Fern leaves are typically envisioned as compound (also termed dissected or divided) with pinnae or pinnules arranged along a central axis (the rachis or costa) (Figure 5).
What type of leaf is a fern leaf?
The leaf (also known as frond) of ferns is the part of the plant most readily visible to observation. The leaf plan in practically all ferns is pinnate—that is, featherlike with a central axis and smaller side branches—and this is considered to be the primitive condition because of its widespread occurrence.
How do you separate Japanese painted ferns?
To divide the fern, remove it from the soil and cut right down the middle of the fern with the sharp knife. Make sure to cut down the middle of the bulb as well so there are roots on both sides. If the plant is not properly divided, the smaller half of the fern will die.
Can Japanese painted ferns tolerate sun?
