yellow rose of texas

i was just planning on posting this prickly pear flower blooming in my front yard: i saw on some garden show it was known as "the yellow rose of texas". i went to wikipedia to add a garden reference, and was shocked by what i found! i knew the yellow rose of texas was also some random country song, i did not know it was based on a legend of a high yellow hotty (pc for me as i am a high yellow hotty (?) with a very light skinned grandma from texas). wow...you learn something new every day...and, i did not see that coming!
