Daffodils are naturally suited to the growing conditions in Ireland. These hardy, perennial bulbs, whose preferred habitat is deciduous woodland, flower in early Spring before leaves form on the trees. In most positions, Daffodils will naturalize and multiply with ease, requiring little attention for many years.
They flower best when they get a minimum of 6 hours sunlight each day. After flowering the strappy Daffodil leaves provide nourishment for the bulb, so they contain a toxin to deter wildlife from eating them. Narcissus bulbs should be planted in Autumn while there is still some warmth in the soil. Clumps are best divided every 4 to 5 years.
