Mignonette is a sprawling annual usually grown for its spicy-sweet flower fragrance. Mignonette bears small greenish flowers often tinged with copper or yellow. The dense flower spikes become loose and open as they mature.
Mignonette—the botanical name is Reseda odorata—is a good choice for borders where it can be planted in a mass to get the full effect of the fragrance. Mignonette can also be spotted around the garden for fragrance.
Mignonette is best directly sown in the garden in spring. The plant does not transplant well. Mignonette grows best where summers are mild, not hot.
