The most beautiful trees in isolation

Which tree to choose for a small garden?

In a small garden, it is advisable to choose trees with low growth, reaching heights of 2 to 3 m. Some varieties can also be grown in pots.

• The magnolia, with its abundant spring flowering in the shape of a tulip and its ramified habit, is a beautiful decorative tree ideal for small gardens. Its resistance to pollution makes it very suitable for urban areas. Hardy down to -20 °C, it acclimatises to almost all our regions, except for the Mediterranean coast. Magnolias prefer a sunny or semi-shaded position, in cool, humus-bearing soil. Choose a compact variety, such as Magnolia brooklynensis ‘Eva Maria’, which will reach 1.50 m in all directions, the magnolia ‘Black Tulip’, slightly taller, with its purple flowers, or the Magnolia stellata ‘Rosea’ (Star Magnolia), known for its numerous light pink, fragrant star-shaped flowers. They can also be grown in pots.

• The Ginkgo biloba ‘Mariken’, does not exceed 2.5 m in all directions and has a decorative habit, both compact and globose. Its originality comes from its fan-shaped leaves. Its deciduous foliage is light green in summer, then takes on beautiful golden hues in autumn. Very hardy and resistant down to -30 °C, it acclimatises almost everywhere, but it dislikes drought and excessive moisture. It thrives in full sun, in any good deep, fertile, and well-drained soil.

• Small varieties of Japanese maple, not exceeding 3 m in height, such as Acer palmatum ‘Katsuras’, bring charm and originality to small urban gardens that are semi-shaded to shaded. They prefer slightly acidic, well-drained soil. They are also suitable for pot cultivation. The main advantage of Acers lies in their spectacular foliage, more or less dissected and changing colours throughout the seasons, as seen in Acer palmatum ‘Red Pygmy’, or Acer palmatum ‘Orange Dream’.

Fast-growing, it will reach 2 m in spread in all directions, the ideal size for an ornamental tree in a small garden.

Which tree to choose for a medium-sized garden?

In a medium-sized garden, an ornamental tree can enhance a green corner, add character, a splash of colour, or simply provide a restful shaded area. It is easy to plant small to medium-sized trees. Here is our selection of decorative trees for a medium garden:
