Conditioning of Ė Narcissus (Daffodils)
Daffodils produce a sap which is poisonous to all other flowers.
You will see daffodils sold, tied into bundles, placed in boxes and not in water. This is because when they are placed in water they produce a toxic sap in the stem. They must be kept separated at all times.
Ideally condition them for 24 hours, by placing the lower stems in water. Once conditioned, you will need to rinse the stems well, but carefully in fresh water. You can see the discolouration of the water once they have been taken out.
Keep them cool until required for your design.
Cocktail sticks inserted into the base of the stem can be inserted as support before adding to foam displays, where they can be mixed with other flowers.
N.B. Also the daffodil bulbs are very poisonous should never be consumed.
