Daffodils toxic to other flowers?

Some plants very cleverly can inhibit other plants around them from flourishing or growing too closely, including some ferns, black walnuts etc that do this. However, I've not known of daffodils inhibiting other plants, or being toxic to them. Allelopathy is the name given to this growth inhibition of other plants.



I've also not known of problems when they are used as cut flowers, in mixed vases etc, although their thick sap may exude into cut flower water, and help it to get contaminated - although this would contaiminate the water in the vase for their own use too.



Hope this helps. Good luck! Rob

Reply:Do not mix daffodils and tulips together in a vase as fresh cut flowers. Daffodils are toxic to tulips, I'm not sure about other flowers.
