Granddaddy Purple is an indica marijuana strain that goes by many different names, including "Grand Daddy Purp," "Granddaddy Purps," "GDP," and "Grandaddy Purple Kush." GDP is more than a classic cultivar. It’s a cornerstone of cannabis heritage. First bred by Ken Estes in the early 2000s, GDP became a staple across West Coast dispensaries. With lineage from Purple Urkle and Big Bud, it helped define an era where dense structure, deep purple hues, and standout presentation became symbols of quality. GDP also played a role in bridging legacy cultivators with today’s regulated market. From its bold coloration to its unmistakable aroma, it reflects over a decade of patience and craftsmanship.
