It's another Garden Fun Friday!  If you have any gardening fun going on today on your own blog, feel free to join in by putting the link to your blog post in the comments.

Today's game is What am I?  

Can you guess what type of garden plant or animal these are from the clues?

1:

• My leaves are very high in Vitamin A, Vitamin K, Vitamin C, and many other nutrients.
• I have a taproot that brings up nutrients for shallower rooting plants around me.
• Historically I was prized and cultivated for a variety of medicinal properties.  Now I am considered a common weed in the US.

2:

• I hatched from a cocoon.
• In one acre of land, there can be more than a million of my kind.
• The largest one of my kind ever found measured 22 feet long.

3:

• I hibernate over the winter.
• My kind is normally orange and black, but a few are white and black.

4:

• My flowers are symbolic of motherly love.
• My flowers changes sex.  When one first opens, it is male, but after a few days the male parts fall off to reveal female parts.
