Last fall I bought bulbs of the daffodil 'Avalanche' through a coop and the leaves look peculiar to me. They are slow growing compared to my other daffodils, which may not mean anything, but the leaves look mottled in the same way virused things do. The color distinction isn't great but up close the length of the leaves are mottled. Dig them up and throw them out? Thanks for any advice.
