A detailed description of the species in the park could be done only by an expert due to the wide variety of plants and flowers. This is rather a short story written by who lovingly takes care of the park and the gardens by planting, seeding and curing, year after year, all of the botanyc collection, from grass to the centenary trees.


Speaking of the trees and their massive presence due to height, shape and “personality”, it must be said that there are no exotic species but the most representative and elitary local ones are present.

In the past, surrounding the extensive garden, the conifers dominated due to their height (up to 40/50 meters), their shady position behind the hill and their dense population. In the last 30 years nature has adversed their presence by air storms, lightnings and heavy snow in periods other than deep winter.
More than a hundred had to be cut down thus leaving wide areas of an unusual and misterious fashion, close to a nordic landscape.

Common sense suggested not to plant similar trees where old roots still laid so new species were chosen: beeches, red oaks, liquidambers and maples. This choice also gave a more light to the park during winter.
Deciduous conifers where planted along the Mondarello Brook together with the water loving Baldcypresses whose roots, time passing, shape in strange manners.

Hornbeams are the most peculiar and amongst the oldest trees in the park. They form a long alley along the northern walls. Aged 400 and more years. To  preserve the fashion of the alley, they are topped every three years and the young branches are weaved together to form the vault. The hornbeams form also most of the hedges crossing the park in a geometrical way.

The most noticeable tree is the Tulip tree, due to it’s hight and look. Althought it prevails on the other plants it in fact is the youngest of the old trees (about 150 years).

They trace the older plant (XVII century)

There are mainly three kinds of hedges: common boxwood (Buxus sempervirens) surrounding the flowerbeds along the south front and the eastern wall and as decoration of the stairs of the eastern front; hornbeam (Carpinus betulus) along the bounderies of the garden and through the park and the deer pits; at last Taxus ( taxus baccata) along the brook. A rim of Hansa roses along the boundary walls colours in purle and white with it’s flowers and, during the autumn, in red and orange with it’s berrys.


It’s difficult to find out who brought in the otherwise austere park the loveliness of colours given by the flowering bushes. The oldest are the one coloured rhododendrons placed in groups very near to the palace, so to frame it and be visible from the inside.
Being the soil acid and rich of heap of dead leaves and pine needles all the acidofile bushes grow with ease. As a matter of fact rhododendrons and hydrangeas are the real stars of the park. Camellias have recently been planted and are blossoming. Every year new species are chosen to improve even further the colorful effect and to create a wide collection.

The flowering bushes have been probably planted by Anna Lomellini di Aragona wife of General Aimaro Malingri. Being her family from sunny Liguria, she brought along the colours and flowers she loved and was used to paint them in a wonderful manner.

they have lately been planted: the first one (double flower, deep pink, unknown kind) was planted in 1997 and is a gift from Roberto Gabetti to the owner Consolata d’Isola. After living 5 years in a vase in Turin it began to suffer and it was brought to Bagnolo. The cold winter climate (down to -18 C°) was thought to be excessive for camellias.
Fortunately the experiment was a success and this camellia became the first one of a growing collection.

It takes time and passion to have camellias become a significant part of the park but they are growing to become an important presence.

The antique rhododendrons are in three monochrome bushes up to 6 meters high. Entering the garden, under the huge Tulip-tree (liryodendron tulipifera), the first to bare flowers at the end of april, stands a rhododendron with big pink flowers veined in dark reddish-purple, of an unknown kind, probably a hybrid dating to the XIX th century; at it’s left the deep purple R. Ponticum is the last one to flower along with the Fastosum flore plenum can be seen; at last, beside the fountain, stands the snow-white rhododendrons nick-named “antique white”, probably R. maximum of north american origin and imported at around the middle of the XVIII th century.

A low and beautiful rhododendron, of the most peculiar red color, was about to die out but having taken care of it it now stands at it’s best. A son of it now glares it’s misterious colors in another part of the garden.

The oldest rhododendrons have been layered and placed in strategic way. they undoubtly are the most robust and better grown.

The garden has recently been enriched with new kinds delivering even more colours and forming a shining under-wood.

At the beginning the plants were chosen here and there on the market, regardless of the origin and leaving some of them without a name. Today the effort goes in the direction of cataloguing in a strict botanycal manner all the species.

Are also sub-species of rhododendrons and pair with them in beautiful manner creating a flow of glaring colours. They lay by the old bushes and the big trees.

The prevailing colours are purple and red but also deep purple and apricot-like. the yellow and orange tones are given by the recently planted AZALEAE MOLLIS (late eighties) but only the name of few of them is known:

Violet Azalea: Blue Danube
White trimmed in purple Azalea: Martha Hitchcock ( 1990/1995)

Orange Azalea: Alladin scout, late flowering (1984)

Scarlet Azalea: Vuik’s scarlet (1989/2002)
White Az.Mollis: Persil
Deep red Az.Mollis: Hotspur red,
Yellow Az.Mollis: Golden Flare
Orange Az.Mollis: Gibraltar
Deep yellow Az.Mollis: Golden Sunset
Apricot orange Az.Mollis: Lemonade
Red-orange Az.Mollis: Knaphill red


The hydrangeas’ season begins when all the other bushes have lost their flowers, at the end of june, and it lasts till late summer. Blu prevails because the acid soil dosn’t permit other colours (pink ones stay so only for one season, then they change to violet and finally to blu).

The only other ones to remain of same colour for their whole life time are the white ones such as the Paniculate.

White flower: Quercifolia, Petiolaris rampicans, Paniculata grandiflora, Annabelle, Soeur Thérese, Preziosa, Aspera macrophylla, Schnee ball.

Blue flower: Hydrangea macrophylla Otaksa, Europa, Blaumeise, MissHepburn, Nikko blue, and other century old ones of unknown kind.


A couple of words must be said about the bambous and their exotic mood. These plants, most beloved to the owner Aimaro d’Isola, form a small wood in the coldest part of the park, separated from the other plants and bushes by the Mondarello brook. They gently lean over the water, in the shade of the Castello hill.
