About Daffodil

Daffodils are among the few bulbs that thrive on being left alone, naturalising into large colonies over decades. All parts of the bulb are toxic, which is why they are largely ignored by rodents and deer and why they persist where other bulbs are eaten out. The cut stems release a sap that shortens the life of other flowers in the same vase, so they are usually conditioned separately first. Foliage must be left to die down naturally, because the following year's flower is built from what the leaves make after flowering.

Growing notes

  • Foliage must be left to die back naturally for next year's flower
  • Reliable returner in cold climates

Pet caution: Daffodil is listed as potentially harmful to cats and/or dogs. Keep pets from grazing on it, and contact a vet if you suspect your animal has eaten some.
