How long do narcissi last in the vase?
It depends what stage you cut them at. Cut them when the buds are plump and you can enjoy watching them unfurl into full bloom over the course of a week. Cut when the flowers are fully developed, they’ll last several days in a cool room. Narcissi stems ooze sap when cut and this can stop other flowers in a vase with them being able to take up water. If you want to arrange narcissi in a mixed vase with other flowers, cut them to the heights required and leave them in a vase on their own overnight. Once they’ve done their oozing, they can be mixed in with the other flowers without harming them – just remember not to recut their stems to set the whole process off again!
