I've been a member of the EPS for one year, and my
passion for palm trees only grows. This is why I would like to present
to you the area of Lake Geneva, where I reside, and where beautiful
specimens of palm trees can be seen. Climatically, aside from the
Ticino, south of the Alps, our area is the most privileged in Switzerland.
The basin of Lake Geneva benefits from hot and sunny summers; in
fact, Geneva is the sunniest city in Switzerland between May and
September. The winters are often calm with little wind. On the downside,
when fog sets in, it can last for many weeks, especially on the
west half of the lake. This dull weather makes everything seem a
little sad. Under this gray cover, however, the lake is able to
retain the heat energy accumulated in the summer, and the temperature
remains constant, just above zero. The springs and the autumns are
often wet, but this is not an absolute rule. The average annual
minimum in the area is between -8°C and -10°C depending
on the location, which places us in zone 8. One notable exception
was in 1985, when the temperature fell to -17°C on the edges
of the lake.
As a child in Geneva, I liked to walk outside the
city to admire the gardens. One day, I fell nose to nose with two
superb Trachycarpus fortunei that were approximately 5 meters high.
The passion was born! From that day on, my dream was to have my
own house, a garden
and palm trees! Unfortunately, although
there are beautiful Trachycarpus fortunei in Geneva, they are very
rare, which is unfortunate as the climate is favorable for them.
Lack of knowledge about the ability of many palms to resist cold
makes people hesitant to plant them outside; let's hope that certain
courageous people will show the way!
To see the many palm trees around lake Geneva, one
must travel to Montreux, a city that is located close to the east
end of the lake. For decades Montreux has been making enormous efforts
to increase its tourism and spread its image of a green city, with
many species and a benign climate. The palm trees are part of that
image here. The area is called the Swiss Riviera. Many Trachycarpus
fortunei are planted on the edges of the lake and along the streets.
They are also frequently seen in private gardens. There are also
some nice Chamaerops and Butia. Recently two Brahea armata, two
Washingtonia filifera, and a Trithrinax campestris were planted
on the walk bordering the lake. Lovers of other plants will not
be disappointed either, as Mimosas (Acacia delbata), olive-trees,
pomegranates and rose bays may also be seen here, as well as the
In 1998, I had the chance to build my house on the
edge of Montreux; my childhood dream had come true. My enthusiasm
for palms being so great, I already saw the garden filled with them--and
only them. However, after long debates with my wife, I agreed to
plant more than palms alone in the garden. Like any beginner, I
started by making errors. The first one was to plant a Trachycarpus
of 60cm, a Butia of 70cm, and a Jubaea of 120cm that I had bought
a few years before in Ticino, in October. Additionally, with compact
soil that drained poorly and holes hardly larger than the pots,
I really didn't have much chance. To cap it all, the winter of 1998-99
was the coldest in 13 years, with two days at -11°C right after
a period of strong rain and snow. The Butia and the Jubaea rotted
slowly in the spring of 1999. It made me regret my poorly thought
out plantings bitterly. Fortunately, the Trachycarpus withstood
this bad treatment without any problem, and I replanted it in a
larger hole in the spring. I'd learned my first rule: plant at the
beginning of the season, in large holes that are deep and well drained.
I went to Ticino in May in search of a new Jubaea.
Unfortunately, as the large specimens are rare and much in demand,
I came back home with empty hands. Finally, with the help of the
Palm Centre (thank you Martin!) I received a much wished-for Jubaea
in July that I immediately planted it in the garden, in a large,
deep hole with well draining soil. The next autumn, my wife gave
me a second Trachycarpus that measured 180cm. Though I was anxious
to have it in the ground, I'd learned my lesson, and decided to
keep it in its pot for the first winter. For extra caution, I used
rain protection and mulch on the Jubaea to help it through its first
winter. The first Trachycarpus remained without protection. Luckily,
the winter of 1999-2000 was less cold with -8°C and the Jubaea
and the Trachycarpus are in good health.
My last acquisitions are a Brahea armata of 160cm
and a Butia yatay. The Brahea was planted in the garden at the end
of March in a very sandy soil. Like others, I am surprised by its
speed of growth. At the end of May, it had already produced a whole
leaf. I also have many young plants: Brahea armata, Chamaerops humilis,
Sabal minor, Washingtonia filifera, Jubaea chilensis, Syagrus romanzoffiana,
Phoenix canariensis, Trachycarpus fortunei, T. takil and T. latisectus.
My goal is to try acclimating Phoenix theophrasti and Parajubaea
torallyi, which seem to me particularly interesting.

I am like Mr. Eracle a newcomer in palm growing
(since one year). I leave also in the Lake of Geneva area and I
am very happy to learn that somebody in my neighbourhood is sharing
the same hobby. That's thanks to EPS !
In connection with the warming up of our climate,I think our area
is worth making a lot of interesting experiments with hardy palmtrees.
