The endemic plants

The Mediterranean regions have one of the largest plant diversities on the planet and our territory of Haute-Provence is a reservoir of biodiversity that we wish to preserve and show our visitors.

In the garden, a number of plant species including some which are specific to the siliceous soil, can be seen growing next to plants which also grow in the more widespread chalky soils of Provence. This place is an “open-air flower book” and it is impossible to list all the species in this little booklet.

Resistance to summer drought

A number of them have an incredible capacity for survival even when there is no rain at all between 15th June and 15th September, and moreover, they grow in rocky areas.
Among them: Thyme, Savoury, Helichrysum, Dorycnium, Teucrium, Helianthemum and Nepeta.

Spike lavender:
Lavandula spica or lavandula latifolia is the endemic species which can be found at altitudes between 300 and 700 m, as here. Its natural encounter with fine Lavender (Lavandula angustifolia), which grows on the plateaus at over 900 m, gave birth to a hybrid called Lavandin which is cultivated on a large scale in Provence.

Terrestrial Orchids:
Every year, in April and May, we are lucky enough to see several species of orchid in flower. These bulbous plants disappear in summer to survive the lack of water. To keep them alive, we keep several areas of soil untouched.

Annuals and biennials:
Many species die off every year in order to reproduce, by their
seeds, over a cycle of one or two years.
Thus they « travel » around the garden to take over new areas. This means special attention when cleaning the garden, to avoid pulling out the plantlets of those which are really interesting such as the Mulleins (Verbascum), Viper’s Bugloss, Poppies, Echinops…

Practical tip: Preserving wild plants
Seed reproduction is the key to preserving spontaneous species and is the reason why no plants will be pruned or cleaned before the end of their seed reproduction cycle. This is all the more so as seeds, in the same way as flowers, are life-giving for a number of useful insects.
Therefore we strongly advise against scything or mowing all the areas of a garden in order to help preserve these living creatures.
