Description
This Chinese Lilac, the 'Josée' Syringa, is a small, fragrant and very floriferous hybrid which flowers again in late summer. Its appearance is similar to that of Syringa microphylla. All these qualities make it a perfect candidate for small gardens. The bushy shrub produces beautiful clusters of a bright pinkish-lilac colour in fading buds when fully bloomed, which give off an authentic lilac fragrance. It blooms in early spring and again sporadically in late summer or early autumn. This variety also looks good in a small flowering hedge, planted in groups, or even isolated near the house to enjoy its wonderfully fragrant and abundant flowering.
The 'Josée' lilac is a French horticultural creation dating back to 1971, thanks to Georges Morel, an INRA engineer, specialist, and pioneer in in-vitro culture. It is the result of the hybridisation of Syringa velutina, microphylla, and meyeri. All these plants belong to the olive family.
The silhouette forms a rounded, compact, and ramified bush, almost as wide as it is tall. When mature, it will not exceed 2 m (6 ft 7 in) in height with a spread of 1.75 m (5 ft 8 in). Its growth is relatively slow, encouraged by rich and moist soil. This variety blooms abundantly in April-May, a few days before common lilacs, in the form of very fragrant pyramidal panicles, 10 to 14 cm (3.9 to 5.5 in) long, composed of small single flowers, light pink-lilac in colour, and rose-purple buds. These inflorescences are grouped in bouquets at the tips of the previous year's shoots, and again in late summer or early autumn, with the current year's branches producing a few inflorescences. This flowering attracts many butterflies and pollinating insects. Its deciduous foliage, composed of small leaves 3 to 4 cm (1.2 to 1.6 in) long, turns a beautiful yellow colour in autumn.
Whether in flowers, for use in perfume, as part of childhood memories, or even as symbols of significant events, everyone has a good reason to love lilacs, as endearing as they are unpretentious. The 'Josée' Lilac is no exception: hardy, easy to grow in ordinary but well-drained soil, even in cold or dry regions, vigourous and undemanding, it embodies the charm and simplicity inherent to old gardens. It is a major element in the creation of scented gardens, even those of a small size, with its flowering accompanying that of laburnums and pink or white brooms. It can be planted on the edge of a grove, in groups, isolated, or as a free hedge mixed with other species (flowering apple trees, Japanese cherry trees, Chinese almond trees, Japanese quinces, Deutzias, etc.). Its highly fragrant clusters are appreciated in spring bouquets, along with the first garden irises, early peonies, bellflowers, and florist's ranunculus.

Planting and care
The 'Josée' Syringa should be planted from November to March and from September to June. It adapts to any ordinary soil, but prefers well-drained, deep, loose, not too dry, even slightly calcareous soils. A complete fertiliser should be applied every year at the start of vegetation. It is preferable to plant it in full sun or light shade in hot climates, as its flowering is better when it receives maximum light and winters are well contrasted. It is useful to cut off faded inflorescences after flowering to avoid fruiting, which is not of great interest but will exhaust the plant. This will promote a late summer rebloom and a more abundant flowering the following year. This variety blooms on both the previous year's shoots and the current year's branches. However, avoid severe pruning that limits spring flowering, unless your Syringa becomes too large.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
