Just a quick video I made in order to try and help you grow "the world's fastest growing tree" from seed, paulownia tomentosa (empress tree/foxglove tree)!
It seems that soaking the seeds in water on a windowsill, then transferring the seedlings to soil once they sprout/germinate is the most effective method to get these trees growing. Planting them directly in soil also works, but I find that it's not as consistent.
NB: The seedlings do best in soil that is kept very moist, almost wet (certainly too wet for other types of plants).
