Do daffodils stay until June

The last week you'll be able to pick a daffodil depends on the locality. Down here in Zone 7b, we are in the Piedmont area, our blooms are expected on Valentine's Day and we'll see the last of the late season blooms in mid-April. However, up in Zone 3 & 4, I expect that you might see a daffodil still blooming as late as the first days of June.
