Description

Reseda odorata 'Grandiflora' is a compact selection of sweet mignonette that produces large clusters of yellow-green flowers with a sweet and sugary scent. It used to be found in many gardens and this annual plant deserves to be rediscovered: it is a nectar-rich, unassuming, pleasantly fragrant plant, easy to sow and cultivate. It blooms for several weeks in summer, bringing life to borders and sunny beds. The mignonette enhances all the plants it accompanies, both in the garden and in bouquets. This compact variety 'Grandiflora' grows very well in pots on the terrace or balcony.

Reseda odorata 'Grandiflora' belongs to the family of resedas, it is a horticultural selection of Sweet Mignonette. It is an annual plant that germinates, flowers and produces seeds within a few months before disappearing. Probably native to the Mediterranean basin, particularly North Africa, the species is widespread in many regions. It is used in the composition of many perfumes. The 'Grandiflora' cultivar blooms all summer, from June to September-October, depending on the sowing date, if care is taken to regularly remove faded flowers. The plant develops strong, branching stems, initially spreading and then upright, forming a clump about forty centimetres in all directions. The leaves are arranged alternately on the stems. They are entire or lobed, toothed or divided into segments, measuring between 2 and 15 cm long. Those that make up the basal rosette are larger than those on the stems. The inflorescence is a large pyramid-shaped cluster of numerous flowers. The flower has six petals of a pale yellow-green, with the upper ones divided into three narrow lobes. The centre of the corolla is occupied by numerous stamens terminated by large pendulous orange anthers. The flowers are rich in nectar and visited by bees. After pollination, fruits form which are capsules containing seeds. When conditions are suitable, the sweet mignonette self-sows randomly in the garden.

The 'Grandiflora' sweet mignonette is an elegant, generous, yet simple plant. It can be sown directly in the ground in spring, among perennials or small bushes, in a natural garden or a cottage garden. It can be planted in border beds, rockeries, or even in the vegetable garden for cut flowers. Some ideas for associations: with tree mallows, fragrant ornamental tobaccos, four o'clocks, wallflowers ...

Planting and care

Two methods of sowing: directly in place, in April-May (as soon as the temperature reaches 10 °C), or in autumn, under shelter, for planting in the garden after the last frost.

Prepare the bed or border carefully, loosening the soil with a fork and levelling the surface. Sow by broadcasting, lightly covering the seeds or in furrows 2 cm deep, spaced 25 to 30 cm apart. Scatter the seeds in the furrows, 5 cm apart. Cover them with light soil, firm the rows with the back of a rake, and water lightly. Keep the soil slightly moist until germination. If necessary, thin out to leave one plant every 25-30 cm.

Sow in trays or pots: sow the mignonette seeds from March or in September. Protect the young plants from the cold (in a bright room between 10 and 13°C) to transplant them in April-May in the garden or pots, once the risk of frost has passed.

You can also collect the spontaneous seedlings visible at the end of summer, and transplant the seedlings into pots filled with garden soil to plant them in May. Be careful to keep the rootballs intact to avoid disturbing the roots.

Cultivation:

Mignonette appreciates the sun and adapts to any well-loosened and properly drained soil (not too clayey or compact), rather rich and moist. Its roots can rot in excessively wet soil. It grows and flowers easily, sometimes self-seeding, which creates beautiful natural beds that require little maintenance. Remove faded flowers to prolong flowering.

Container cultivation: choose a sufficiently deep pot, at least 40 cm in diameter, with drainage holes at the bottom. Use a mixture of garden soil, potting soil, and well-decomposed compost. Sow, lightly cover with fine soil, firm and water regularly. Keep only three plants per pot. The tips of the shoots can be pinched to encourage branching. Use flowering plant fertiliser in the watering water.
