The rose was discovered on the fresco of "L’oiseau bleu" dating from the 18th century BC. And it was not until the 12th century that rose cultivation began in France.

In fact, it is planted first for its fragrance, then its edible properties, then for its medicinal properties, and finally for its ornamental qualities.

It is Joséphine de Beauharnais who introduces 250 varieties of roses in her garden in Malmaison.

Currently, the rose is without context the Favorite flower of the French who acclaim it for its exceptional beauty and fragrance.


It is a poisonous plant in all parts due to the presence of cardiotonic glycosides in bay laurel.

It consists of oleandrine, a heteroside with a steroidal structure, pharmacologically and chemically similar to ouabain, as well as digoxin, two-cardiotonic components frequently used in heart failure.

The action of the oleandrin compound is twofold. It allows the interaction with the Na + and K + pump system of the heart muscle cells and the activation of vagal tone to optimize the nerve regulation of the heartbeat.

This is because the spread of cancer cells requires excellent functioning of the Na + K + pumping enzyme system in order to reproduce properly in the human body. As a result, this system forms the basis of new anti-cancer drugs such as the oleandrine in oleander, which has already been in promising trials in humans.

In addition, the consumption of a single leaf of this plant can be fatal for humans, whether adults or children, because of the serious problems often caused by its ingestion.

A notable fact is the roasting of pieces of lamb by Napoleon's soldiers on oleander spits in 1808 during a bivouac, which caused the death of 8 out of 12 soldiers, the other 4 being seriously intoxicated.

Animals, such as herbivores, can also poison themselves with oleander leaves. Dry leaves are the main cause of this since they consume very little fresh leaf.

It has been determined that an amount of a few tens of grams of fresh leaves (30 to 60 g) would be fatal for an adult cattle, while 4 to 8 g of leaves would be sufficient to cause the death of an animal such as sheep.

Likewise, the water in which the leaves, roots or branches of oleander have been soaked is toxic to animals.


Tips for cutting oleander

If the soil is heavy, feel free to also incorporate a handful or two of additional sand to lighten it. Water copiously this substrate, and go to the foot of the bay leaf cuttings !

Preparation of cuttings

Using a secateurs (with a clean and disinfected blade), remove young twigs about fifteen centimeters in length.

Remove all of its leaves except the 3 to 4 terminals.

Then reduce them by half. This trick, also used for shrubs with large leaves such as hydrangea cuttings, reduces evaporation, and therefore avoids drying out of the cutting.

It is used to cut many other shrubs or climbing plants because it significantly increases the chances of recovery. Under a closed atmosphere, the cuttings are indeed less likely to dry out.

How to water the cuttings?

After a few days / weeks, if any leaves are starting to turn yellow or appear to be sick, do not hesitate to remove them. cuttings incriminated: they will not take root.

Under protective atmosphere

Finally, don't forget that the bay leaf is a cautious species, especially when the plants are young. In cool regions, do not hesitate to bring in cuttings under a veranda or in a horticultural greenhouse to bathe them in a gentle atmosphere. Elsewhere, place the pot at the foot of a wall, in the shade all day.

When to transplant them into the ground?

When the signs of recovery appear (appearance of new leaves, roots that come out through the drainage hole), it is time to repot them individually. Then wait until the next spring. Once the last risks of frost have been eliminated, you can plant them permanently in the ground, in their planned location.

During the winter, however, you will have taken care to protect these young people under a wintering veil.
