After searching, he found a rare patch of pink bluebonnets in Bexar County, Texas. When these bluebonnets reproduced, he culled out the lighter pink ones, and left the darker reddish ones. A few generations later he obtained maroon bluebonnets. These maroon bluebonnets that he cultivated will be on the market after the 1999 crop matures. It took 15 years of selective breeding to get a maroon color trait to stand out in enough bluebonnets to sell on the market.
Selective breeding is a slow and tedious process, but it works.
