I bought a package of Peruvian Daffodil bulbs on impulse today. Now I'm wondering if it was a wise choice, even though they look so pretty on the package and what I've seen of the flower images on the 'net. Come to find out, they aren't hardy in my zone 4, and I will need to dig the bulbs up in the fall and bring them inside until spring again. So, have any of you who are in zone 4b, actually left the bulbs outside during the winter? I'm assuming that if I were to do so I would have to mulch them very heavily. Maybe it wasn't so smart of me to buy these on impulse, but the picture of the flowers looked so pretty, and it said "fragrant" as well! :/ Thanks!
