The lilac
The lilac perfumes the gardens from April. Its blue, purple, pink or white flowers in clusters are a visual and olfactory wonder. It appreciates neutral to calcareous drained soils and sunny exposures to bloom well. Very hardy, it resists to temperatures of -20°C.
The skimmia
The skimmia is a very ornamental shrub by its splendid and fragrant spring flowering in white stars, followed by flamboyant red berries which will color your winter. The skimmia likes neutral to acid soil and does not tolerate limestone, it appreciates half-shade. Hardy and resistant to diseases and pests, it is an ideal subject for beginners.
The Japanese hornbeam
The Japanese hornbeam is an ideal shrub for mixed hedges or as an isolated subject. It can reach 3m in height and is adorned with golden yellow pompons in spring. Hardy, resistant to almost everything, easy to grow, it appreciates drained and fertile soils and a sunny exposure.
Sarcococca
Sarcococca is an evergreen shrub, precious for its bewitchingly fragrant bloom in the middle of winter.

An ordinary, neutral to acidic, well-drained soil and a semi-shaded exposure will suit it perfectly.

The broom
The broom will find its place as well in free hedge as in bed or in rockery. Its delicately scented bright yellow flowers signal the return of the beautiful season. In full sun in neutral or acid soil, it will grow even if the soil is poor and very drained.
