Tulip's lesson

Bulbs buried in cold, hard ground when seasons
   changing like the sun setting.
Life moves on, things are forgotten and there is
    no sign of life over thevpotted plant.
Slowly as the renewal time if spring seeps thru
    a blade of green fights thru.
Earnest efforts are rewarded in the amazingly,
     beautiful bloom in the daytime and the wise
     close at night.
