Anna Taylor of Floral Notes shares an important tip for flower arranging with daffodils:

“Top tip - narcissus entirely on their own, in a jar of water, for a few hours. You know that sticky sap that leaks from the stem when you cut them? Well that stuff is toxic and what shortens the life of flowers in water with them. Instead, in a vase of water, the toxic sap will run out and seal. Just don’t cut the stems again otherwise you’ll need to do this again. This way you can arrange any spring flowers together and the narcissus won’t reduce the vase life of every other stem!”
