Mignonette Flower Care

Size & Growth

Reseda plants have a relatively fast growth rate and don’t take too long to germinate and reach their full height.

The genus comprises 41 accepted species reaching a height of 1’ – 4’ feet.

The leaves can vary from species to species.

They grow from a basal rosette of foliage at the ground level.

The stem leaves then arrange spirally up the stem and are toothed or pinnate.

They are on the smaller side growing up to 6” inches in length.

Flowering and Fragrance

Reseda plants have been grown as fragrant flowers for the garden since the early Victorian times.

The flowers on the Reseda species come in shades of green, yellow, and white with orange stamens.

They are produced on slender spikes and usually have 4 to 6 petals on each.

Each flower is pretty small i.e., roughly ¼ inch in diameter.

The most notable feature of the flowers is the fragrance emitted from them.

It’s described as ambrosial and can sweeten up any area they are planted in.

The plant produces fruits, small dry capsules, containing several seeds.

Light & Temperature

Reseda plants are half-hardy.

They do well in USDA zones 1 to 9b or 10 in colder regions.

As for sunlight, they can grow in both full sun and partial shade areas in the garden.

The optimal temperature for most Reseda plants is around 70° degrees Fahrenheit (21° C).

Watering and Feeding

Unlike some other perennial and annual species, the Reseda genus doesn’t do well in drought conditions.

It requires moist but well-drained soil.

Water the plants regularly, avoiding overwatering them.

Too much water or soils with poor drainage is harmful and cause root rot instead.

Even though Reseda plants are not too picky about soil, they do exceptionally well when the soil is rich.

If the soil isn’t rich, feed it once a month to add nutrients.

Soil & Transplanting

Reseda plants love soil rich with nutrients with a pH leaning towards the alkaline side.

The preferred pH for Reseda plants is between 6.0 and 8.5.

While the plants love enriched soils, they are not too choosy and can grow in other kinds of soils as well.

When it comes to moving plants, Reseda doesn’t transplant well.

It’s better for the plants’ health and growth to place them directly where you want them and thin them out when the seedlings are very young.

Grooming and Maintenance

As mentioned before, Reseda plants don’t respond well to transplanting.

Hence, it is better you sow them directly at the location where you want to place them.

It’s important to pinch back the tips of young Reseda plant to promote branching and abundant flowering.

How to Propagate Reseda

Reseda plants are best propagated when grown from flower seeds sowed directly in the ground.

  • Sow the seeds from the beginning of spring until the first half of summer.
  • The seeds should be sown on the surface in a partially shaded area in neutral, rich soil.
  • As for spacing, it depends on the species and variety of the plant you choose.
  • Smaller species are placed 6” – 8” inches apart from one another while larger species are placed approximately 12” inches apart.

It will likely take about three weeks for the seeds to germinate.

Start the plants indoors, but the plant will do better when the seeds are sowed in the ground or wherever you want to stay permanently.

Sweet Reseda Pest or Disease Problems

Reseda plants are susceptible to a fungal disease called Verticillium Wilt.

The disease is caused by soil-borne pathogens and is prevalent in tropical and temperate climates.

It’s managed by removing affected pants or pruning the damaged areas.

Common pests like aphids can damage the plant.

Use a pesticide to get rid of the aphids or consult your local garden center or nursery for a less harsh solution.
