That purple pigment pattern is really unique, I'm guessing a genetic trait It reminds me of the multi color bud that fruity pebbles originated from the most expensive seeds ever sold (no official name) but its supposedly visually a technicolor. Seeds sold for $3,000-$5,000 in 2012 I think these seeds are the progenitors of fruity pebbles. Holds the Guinness world record for most expensive seeds ever sold.
