Hulled Hemp Seed Hearts are gorgeous green and cream coloured seeds with a mild nutty flavor and creamy texture. Because of their high oil content, hemp seeds should be stored in an airtight container in the fridge or freezer to stay fresh. Hemp seeds and marijuana come from the same species of plant, but are different varieties and the similarities stop there. Hemp seeds do not contain THC (tetrahydrocannabinol), the active substance in marijuana.
