Autumn Colour

At the opposite end of the country from Berlin lies Lake Constance at the point where Germany, Switzerland and Austria meet up. With a surface of 473 square kilometers, it is the third largest lake in Central Europe and crossed by the Rhine. Recent reports have revealed its water quality to be so clean, that it can no longer sustain its fishstocks.

At the south-eastern end of the lake, not far from the town of Constance, lies the small Island Mainau covering 45 hectares. Here lies one of Germany’s best-known garden treasures. At the northern end of the island sits the house, built in 1746, owned by the Bernadotte family. The Grand Duke Frederik 1st of Baden acquired the property in 1853, and that is where its garden history began. He developed the parkland by planting an arboretum with trees he collected on his travels. Successive generations have continued to develop the garden. Its unique climate allows them to grow many plants which in any other part of the country would need frost protection. Being a small island surrounded by a large body of deep water, the climate is exceptionally mild. During our visit today, the morning mist over the lake slowly evaporated, but even by lunch time there were still smoke-like traces hanging over the rose garden diffusing the autumn sunlight beautifully.

Garden features

The level of craftsmanship on show in this garden is quite unique. Everything is done by the in-house team of skilled people. Four designers are full-time employed to work out planting plans and design and build new features. The garden staff of over 80 sees to it that every morning the paths are swept, beds are maintained in perfect order, the tree collection is well maintained, the fruit tree plantations of over 7 hectares are seen to and the nursery with its collections of orchids and tender plants are doing well.

Building work is carried out by their own team, and that to the highest standards with the best materials. Walls, steps and paving show great craftsmanship and great detailing, using fine materials.

The Arboretum

The park contains many spectacular specimen trees that are beautifully maintained. A stand of Thuja plicata planted in 1864 has developed into magnificent trees with beautiful stems. Nothing to do with dull-green hedges! These and many other special conifers provide a wonderful green contrast to the glowing autumnal colours of buttery yellow Liriodendron tulipifera or the numerous reds of Liquidambar styraciflua. Everywhere hang the delicious smelling clouds of burnt caramel of the Cercidiphyllum japonicum which feel so much at home that they have selfseeded themselves throughout the garden. An impressive avenue of Giant Redwoods Metasequioa glyptostroboides takes the visitor up towards the house. They are already massive, they will become breathtaking as time goes on and they continue to gain in height.

Rose garden

A formal rose garden next to the house is as formal rose gardens tend to be in the autumn, no longer at their best. I find this is always an interesting time to see which roses are still doing well. Tired after a long summer, standard roses particularly show up their weakness now that there are no longer the flower masses to detract the eye: straggly growth emerging from a knobbley graft.  The way to avoid this is by planting climbers grafted onto stems. Here the lovely old climber ‘Alberic Barbier’ has developed into a large umbrella of foliage, so there was not a knobbley knee in sight.

One rose that really stood out for its amazing abundance is ‘Fortuna’ a low growing   floribunda rose still covered in a mass of single pink flowers, with hundreds of buds still to come.

Dahlias

Dahlia ‚Baby Blue‘

Below the parkland lies a huge flower garden. Part of it is dedicated to large shrub roses, part of it is a huge herbaceous and grasses garden, part of it are giant dahlia borders. All perfectly staked and regularly dead-headed so that even this late in the season the sheer the scale of them with a colourful backdrop of autumn colours they take your breath away. ‘Baby Blue’ is a tiny pompom dahlia with pink flowers that caught my eye due to its exceptionally small flower.

The generous use of grasses in the herbaceous garden mixed with asters, late anemones and the last of the Aconitums make this garden also worth its while.

Bedding

The garden is best known for its bedding displays, and these draw the thousands of visitors on a daily basis. These are also the reason why the plant-loving garden visitor may be frightened off from visiting this garden, be it unjustified. Yes, there are brightly coloured bedding displays whose designs and themes change from year to year. There are three dimensional figures planted up with bedding scattered about. They are befitting of a 19th century garden and would have been a dominant feature in most of them, but regrettably have vanished from most gardens as nobody can afford it anymore. It is the most labour-intensive form of gardening that exists and that is precisely why, it is rather nice to indulge in this sort of garden once in a while as in combination with everything else on offer here, the visit always proves enriching especially on a sunny autumnal day.

Go and visit: the garden is open every day of the year, from sunrise to sun set.

Über Isabelle Van Groeningen

Dr. Isabelle Van Groeningen – Zur Person Isabelle Van Groeningen ist eine international anerkannte Gartenhistorikerin, -designerin und –beraterin, die ihre langjährige Erfahrung in diesen Bereichen sowohl durch Vorlesungen und Vorträge als auch durch schriftliche Beiträge in der Fachliteratur weitergibt. 1983 übersiedelte sie von ihrem Geburtsland Belgien nach England, um Horticulture an den Royal Botanic Gardens Kew zu studieren. Nach erfolgreichem Abschluss mit dem „Kew Diploma in Horticulture“ fertigte sie ihre Doktorarbeit im Fach historische Garten- und Landschaftsrestaurierung an der York University an. Ihr besonderes Interesse gilt der Anordnung von Stauden im Garten, von der traditionellen englischen Staudenrabatte bis hin zur lockereren ökologisch-orientierten Pflanzweise, wie sie in Deutschland und den Niederlanden praktiziert wird. Gartendesign 1992 gründete Isabelle Van Groeningen zusammen mit Gabriella Pape die Firma Land Art Ltd., deren Projekte seit Anbeginn einen weiten Bereich abdecken und sich – je nach Auftraggeber und Situation – mit historischen ebenso wie modernen Gartenanlagen befassen. Im Jahre 2000 gewann Land Art Ltd. bei der Hampton Court Flower Show eine Goldmedaille und die „Best in show“-Auszeichnung für den bis dahin größten Schaugarten mit dem Titel „Go Organic“. Dazu kam 2007 die zweithöchste Auszeichnung, eine „Silver Gilt“–Medaille, bei der weltberühmten Chelsea Flower Show für einen im Auftrag des Daily Telegraph geschaffenen Schaugarten: ein von Karl Foersters Senkgarten in Bornim bei Potsdam inspirierter Garten. Isabelle Van Groeningen hat sich schon frühzeitig dem biologischen Gärtnern verschrieben und sich zum Ziel gesetzt, umweltfreundliche Gärten schaffen. Dabei ist zum Beispiel der sparsame Umgang mit Wasser ein wichtiger Faktor sowohl bei der Gesamtgestaltung des Gartens als auch bei der Auswahl der Pflanzen.
