I planted three bulbs last spring. Each is coming up double nose this spring. About a week after the Martagons here. It was 27' F one morning a couple days ago and no frost damage. If I get a night where it's forecast to go down into the 20's again, I'll cover all but one nose with oak leaves and monitor for damage. I'd like to know how much frost this one will withstand before damage. Zone 5B/6A here in Southeast Wisconsin.
