Odorata

Reseda odorata

flower

Mignonette is a delicate annual or short-lived perennial prized for its intensely fragrant, inconspicuous flowers that bloom in dense spikes. The plant is modest in appearance with small greenish-yellow to reddish flowers, but produces one of the most powerful and sweet fragrances in the garden. Historically a cottage garden favorite, it attracts pollinators and is often grown as a cut flower for fragrance.

Growth Stages

1

Germination

7-14 days

Tiny seedlings emerge with fine cotyledons and first true leaves. Very delicate at this stage.

Keep soil moist and provide bright light. Thin seedlings to proper spacing once they have 2-3 true leaves.

2

Vegetative Growth

3-4 weeks

Plant develops bushy foliage with narrow, slightly wavy leaves. Low rosette-like growth before flowering begins.

Water consistently. Do not overwater. Light feeding with balanced fertilizer encourages foliage. Remove flower buds to extend foliage growth if desired.

3

Flowering

4-8 weeks

Dense, elongated flower spikes emerge from the leaf axils with small, greenish-yellow to reddish flowers. Fragrance is strongest in cool evenings.

Deadhead spent flowers to encourage continuous blooming. Water during dry periods. Provide afternoon shade in hot climates to extend bloom period.

4

Seed Set

2-3 weeks

Flowers fade and small seed pods develop along the spike. Plant may begin to decline in hot weather.

Allow some flowers to remain on plant for seed collection if desired. Cut back and deadhead other stems to potentially encourage more blooms.

5

Decline/End of Season

Variable; plant dies after seed set

Plant weakens as summer heat increases; foliage yellows. Flowering slows significantly in heat.

In cool climates, deadhead and water to maintain blooms longer. In hot areas, consider removing and replanting for fall bloom. Self-seeds readily if allowed to mature.
