Sunflower sprouts usually refer to soaking hulled sunflower seeds overnight, whereas the greens take about a week to grow, and must be grown with unhulled sunflower seeds. Sunflower greens are 25% protein and on an ounce per ounce basis have a similar protein count to chicken. This makes them an awesome food for vegans and also explains why they have a meatier taste than other sprouts. If you haven’t tried these I can tell you that many people regard them as their favorite sprout because of the taste, myself included.
