can I sprout these in mason jars? Or do I have to plant them?

These will sprout in mason jars but they are better sprouted straight up in a tray for 6 plus days , there are other methods that are better for sunflower greens , you can also use soil inside in a tray :-)

When should these be planted, if planting outside?

it all depends on your region, do a search for your area and temperatures for each variety of plant and plant accordingly :-)

Will these sprout outside in a barrel where I have planted sunflower seeds in the past?

these are sproutable seed, whether you grow them as a microgreen or plant outside they will grow :-)

What species are your sunflower black oil seeds? If planting outside how tall do they get?

these are Helianthus Annuus, we only grow for micro green use, you can plant them outside etc.. we have no expertise in outside growing to a plant on ly sprout/microgreens.
