Welcome to another edition of Bud Facts! This week our cannabis spotlight falls on a heavy Indica strain that some users report literally tastes purple.

Grandaddy Purple, or GDP, is a California staple – it is a famous genetic cross of Big Bud and Purple Urkle, two well-known, powerful Indica strains.

Ken Estes created Grand Daddy Purple back in 2003 in search of the ultimate indica-hybrid. Ken had previously discovered the therapeutic benefits of medical cannabis after being paralysed from the waist down in a motorcycle accident in July 1976. He became an activist in the 90s, working with Dennis Peron and others before opening his own Medical Marijuana Collective in Concord, California.


Granddaddy Purple has a purple tint and an unmistakable smell. With a deep, dark purple hue and violet sugar leaves mixed with dense, light green nuggets.

The taste is a mixture encompassing complex grape and berry aromas that people have reported tastes purple.

The strain also inherited it’s oversized, compact bud structure from its Big Bud parent.


Granddaddy Purple is used to treat:

  • – pain
  • – stress
  • – appetite loss
  • – muscle spasms
  • – joint pain
  • – migraines 

It is also nicknamed “The Night-time Strain” because it’s so good at treating an array of sleep disorders. 


One of the things we love most about cannabis is how many strains there are, all with their own flavours, appearances and effects. Classic strains like Grand Daddy Purple have also inspired other great strains since, such as Purple Envy by Gorilla Seed Bank.
