ferns.


 
ferns are my favorite & I am so excited to bring mine out for spring this week.
all about ferns:
  • Ferns belong to a group of plants called featherplants or pteridophytes, along with club mosses and horsetails.
  • Coal is made largely of fossilized featherplants of the Carboniferous Period.
  • There are now 10,000 species of fern living in damp, shady places around the world.
  • Fern leaves are called fronds. When new they are curled up like a shepherd’s crook, but they gradually uncurl over time.
  • Ferns grow into new plants not from seeds but from spores in two stages.
  • First spores are made in sacs called sporangia. These are the brown spots on the underside of the fronds. From these spores spread out. Some settle in suitable places.
  • Second spores develop into a tiny heart-shaped plant called a prothallus that makes male and female cells. When bathed in rain, the male cells swim to the female cells, fertilizing them. A new root and stem then grow into a proper fern frond and the tiny prothallus dies.
