I planted these seeds in seed starter mix, put them under grow lights, and literally within 2 days they had already sprouted. I've never seen ANYTHING sprout that fast. They are doing GREAT. Actually, I think I planted them too early because now they're going to be big before it's time for me to put them outside. No worries though. I'll plant a 2nd round. I'm just impatient and having major spring fever. I would DEFINITELY buy these again. They're the fastest growing seeds I've ever bought, and I have a HUGE English cottage flower garden.
