There are also “symbiosis or competition” relationships in the plant world. For example, when calendula and rose are planted together, they will make the rose healthier. Lily and rose are together can prolong the flowering period.
Cloves and lilies of the valley, cloves and daffodils, daffodils and lilies of the valley, etc., should not be kept together, or these plants will not survive. The substances secreted by the leaves and roots of oleander will cause damage to other flowers. Hydrangeas and jasmine, dahlias and rose cannot be grown together, and if kept together for a long time, one or both will be harmed.
