Jasminum grandiflorum, the large-flowered jasmine

Do you know what a bottle of J'adore by Dior has in common with the Himalayas? Spanish jasmine (in Latin, Jasminum grandiflorum). This plant of the Oleaceae family has left Asia and its mountainous regions to become the star ingredient for perfumers.

How to recognize Jasminum grandiflorum?

Jasminum grandiflorum, or large-flowered jasmine, is a shrub with a bushy habit. It grows to a maximum height of four meters and a width of over two meters. Like its cousins, jasminum sambac and jasminum officinale, it climbs and curls up when offered support. Fast-growing, it can cover an arbour, low wall or pergola.

Its branches change color over time. Woody stems are born green. As they age, they turn brown.

Spanish jasmine has deciduous or semi-evergreen foliage. When temperatures remain mild, it retains its leaves. But if the mercury drops, so do the limbs! Its green leaves measure from five to twelve centimetres. They are composed of an odd number of leaflets (between five and eleven) arranged alternately. The last one, lanceolate and acuminate, sits at the end of the rachis.

Jasminum grandiflorum is best appreciated for its four-centimetre-diameter flowers. They bloom between May and September. Bouquets of white flowers with pink undersides appear. With their five petals, they resemble stars.

Jasminum grandiflorum is non-toxic. It's a melliferous plant that delights bees. And perfumers. Its fruity, powdery fragrance is used in many perfumes. Although natural essence is gradually being replaced by synthetic versions, large-flowered jasmine continues to be cultivated in Grasse to produce a number of luxury fragrances.

Our maintenance tips

Hardy, jasminum grandiflorum can withstand winter frosts. Just be sure to protect them from the cold so that the stump doesn't die, and don't expose their flowers to too much sun. They may burn.

Watering

Jasminum grandiflorum appreciate freshness. Their soil must be kept slightly moist in spring and summer. But the plant doesn't like excess. Be careful not to soak the substrate!

Provide water at room temperature, without lime. You can, for example, collect rainwater or use filtered water.

Once you've watered your Jasminum grandiflorum, empty any stagnant water from the saucer or planter. It may rot the roots.

Spray

Brumisez le feuillage avec une eau non calcaire améliore l'hygrométrie et lutte contre les attaques de nuisibles.

Repotting

Every spring, repot your Jasminum grandiflorum to give it more space.

Soak the root ball of your Large-flowered jasmine until the air bubbles disappear.

Choose a pierced pot, preferably terracotta, and a support (stake, trellis, dome or tower) to which the plant can wrap itself. Jasminum grandiflorum grow quickly. You can use a container two to four times larger than the previous one, especially if you're repotting after purchase.

Line the bottom with a bed of gravel or clay balls to optimize drainage. If you need to plant your stake, do so now.

Add a layer of substrate. Choose a rich, light mix, such as potting soil for Mediterranean plants or garden soil with sand.

Place your Large-flowered jasmine in the center. Place the vines on the substrate. Fill with potting soil and press gently to remove air bubbles. Water for the first time to encourage rooting.

Fertilization

To promote the growth of your Jasminum grandiflorum, apply fertilizer in spring and summer.

Add flowering plant fertilizer to watering water.

Prune

Start by removing wilted flowers.

Then, using clean, sharp pruning shears, cut back dead branches.

You can shorten the others by ten to fifteen centimetres to control the plant's development.

Pinch

Pinching improves branching. When new leaves appear, take them between your fingers. Section the leaf with your fingernails.

Plantation

When the risk of frost has passed, it's time to plant.

Choose a location in partial shade and sheltered from the wind. Jasminum grandiflorum are climbing plants. Set them up next to a wall, pergola or arbour, or provide them with a support to wrap around. Is your soil heavy and compact? It's best to loosen it before planting your Large-flowered jasmine.

Soak the root ball while you dig a hole three times as big. Place pebbles or sand at the bottom for drainage, and compost or fertilizer for growth.

Plant your specimen in the center. The root ball should be three centimetres below the ground. Fill in with your garden soil.

Tamp gently to avoid damaging the roots, then water. You can mulch the soil to keep it cool and limit watering.

Cutting

Cutting is carried out during the strong growth phase, generally in spring and early summer.

Using a clean, sharp tool, such as scissors or pruning shears, remove a ten- to fifteen-centimeter stem with at least two nodes and three levels of leaves. Remove the lower limbs, leaving only the terminal pair.

Immerse the lower part of your cutting inclear water at room temperature. Make sure the level remains even and the liquid clean.

Protect your cutting from direct sunlight.
