Pinus parviflora Negishi - Japanese White Pine

Pinus parviflora 'Negishi' is a very beautiful form with a twisted silhouette and grey-blue foliage of the Japanese white pine. Slow-growing and of modest stature, it is only after many years that it will adopt its characteristic, widely conical and irregular habit. It is also appreciated for the beauty of its foliage, with strongly twisted needles that form like grey-blue brushes on its short branches. This variety will be able, from a young age, to produce pendulous and decorative cones that will persist for a long time on the plant. This conifer deserves a prime location in the garden, as a solitary specimen. Undemanding and very frugal, it prefers sun and well-drained soils but can tolerate mediocre soils and withstand drought once well established.

Pinus parviflora, also known as the Japanese white pine or five-needle pine, is a plant of the Pinaceae family native to forests located at altitudes between 1300 and 1800m (4265 - 5905ft), in the Japanese islands. In its natural environment, this species exceeds 20m (65ft 7in) in height and has a pyramidal habit, often as wide as it is tall, bearing a dense, conical crown. Appreciated for its wood in Japan, this elegant species has given rise to very beautiful forms, often cultivated as bonsai.

An ancient Japanese selection, the 'Negishi' variety, derived from this species, stands out for its more modest growth, its beautiful blue-silver foliage, and a unique Japanese-inspired habit. This small tree has an upright silhouette with irregular ascending branches during its early years. Over time, it develops a more rounded and still very dense habit due to its needles persisting for 4 years. Its growth is slow, so that at 20 years old, it will not exceed an average height of 3m (9ft 10in) with a 3m (9ft 10in) spread. The trunk is covered with a smooth bark of grey-violet colour, which darkens and peels with age. The branches are short, brownish-green, sometimes slightly fuzzy. They bear medium-sized needles measuring from 4 to 6cm (1.6 - 2.4in) in length. They are slightly curved, grouped in fives and arranged in dense, helical tufts. In spring, the young shoots have a blue-silver hue, emerging from a darker green-silver foliage. The reflections perceived are due to the presence of blue and silver lines on their green background. Young specimens already flower and produce green-blue cones that somewhat resemble tightly packed artichokes. They are solitary or grouped in small clusters, pendant, hanging on a peduncle.

Japanese white pines are unjustly unknown to gardeners: their cultivation presents no difficulty, they are resistant to cold, tolerate some drought, and are very accommodating with regards to the soil as long as it is properly drained. Pinus parviflora 'Negishi' will find its place in all gardens as its Japanese origins do not prevent it from thriving in very different climates. This timeless small tree will stand out when planted as a solitary specimen and will also bring majesty to a medium-sized garden. With its moderate growth and its very Japanese-like silhouette, it will of course be a magnificent feature in a Japanese garden. It pairs well with large stones, the geometric lines of pools, and masonry work. It can be associated with bamboos and Japanese grasses Hakonechloa macra, in a very 'zen' spirit. The true graphic qualities of conifers naturally impose themselves in the design of a contemporary garden, which prefers the aesthetics of forms, silhouettes, and textures to the dance of blooms. These plants, with their reassuring permanence, structure a bed, mark pathways, and enhance the garden in winter. The key is to play with volumes and colours.
