Strange Yellow Tulip Growing in our Yard

I love my beautiful flowers. This lonely strange yellow tulip is growing in our yard. We did not plant this flower, so we really are not sure how it got here. We have plain yellow, red, red with strips and yellow with strips and this one 1/2 and 1/2 tulip.

According to Teleflora,"Although different tulip colors carry distinct meanings - yellow tulips symbolizing cheerful thoughts, white conveying forgiveness and purple representing royalty - a Turkish legend may be responsible for the red tulip's symbolism. The story goes that a prince named Farhad was love struck by a maiden named Shirin.  When Farhad learned that Shirin had been killed, he was so overcome with grief that he killed himself - riding his horse over the edge of a cliff.  It's said that a scarlet tulip sprang up from each droplet of his blood, giving the red tulip the meaning "perfect love.""
