Pinus thunbergii (syn: Pinus thunbergiana), the black pine, [2] Japanese black pine, [3] or Japanese pine, [4] is a pine tree native to coastal areas of Japan (Kyūshū, Shikoku and Honshū) and South Korea. [5]
It is called gomsol (곰솔) in Korean, hēisōng (黑松) in Chinese, and kuromatsu (黒松) in Japanese.
Black pines can reach the height of 40 metres (130 feet), but rarely achieves this size outside its natural range. The needles are in fascicles of two with a white sheath at the base, 7–12 centimetres (2+3⁄4–4+3⁄4 inches) long. Female cones are 4–7 cm (1+1⁄2–2+3⁄4 in) in length, scaled, with small points on the tips of the scales, taking two years to mature. Male cones are 1–2 cm (1⁄2–3⁄4 in) long borne in clumps of 12–20 on the tips of the spring growth. The bark is gray on young trees and small branches, changing to black and plated on larger branches and the trunk; becoming quite thick on older trunks. [2] [3] It is a widely adapted plant with attractive dark green foliage. [6]
In North America this tree is subject to widespread mortality by the native American pinewood nematode, Bursaphelenchus xylophilus , spread by means of beetle vectors. Subsequently, blue stain fungus invades the plant, leading to a rapid decline and death. This nematode has also been introduced to Japan accidentally, leading to the species becoming endangered in its native area.[ citation needed ]
Because of its resistance to pollution and salt, it is a popular horticultural tree. In Japan it is widely used as a garden tree both trained as Niwaki and untrained growing as an overstory tree. The trunks and branches are trained from a young age to be elegant and interesting to view. It is one of the classic bonsai subjects, requiring great patience over many years to train properly.[ citation needed ]
One characteristic of the Japanese black pine that makes it desirable for bonsai, is the possibility of inducing a second flush of new growth and improved ramification in a single growing season. Unlike most pines, which are single flush plants, the Japanese black pine can be induced to produce new buds at the base of each spring candle by simply cutting the candles at the base as they elongate, a technique called decandling. This technique will result, in a few weeks, in the flush of multiple new buds at the base of the cut candle; each of these new buds will result in turn in new candles and branches. [7]
A pine is any conifer tree or shrub in the genus Pinus of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae.
The Douglas fir is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir, Rocky Mountain Douglas-fir and Mexican Douglas-fir.
Pinus sabiniana, with vernacular names including towani pine, foothill pine, gray pine, bull pine, and digger pine, is a pine endemic to California in the United States. Some sources discourage using the name "digger pine," considering it pejorative.
Pinus mugo, known as dwarf mountain pine, mountain pine, scrub mountain pine, Swiss mountain pine, bog pine, creeping pine, or mugo pine, is a species of conifer, native to high elevation habitats from southwestern to Central Europe and Southeast Europe.
Pinus nigra, the Austrian pine or black pine, is a moderately variable species of pine, occurring across Southern Europe from the Iberian Peninsula to the eastern Mediterranean, on the Anatolian peninsula of Turkey, Corsica and Cyprus, as well as Crimea and in the high mountains of Northwest Africa.
Pinus jeffreyi, also known as Jeffrey pine, Jeffrey's pine, yellow pine and black pine, is a North American pine tree. It is mainly found in California, but also in the westernmost part of Nevada, southwestern Oregon, and northern Baja California. It is named in honor of its botanist documenter John Jeffrey.
Pinus rigida, the pitch pine, is a small-to-medium-sized pine. It is native to eastern North America, primarily from central Maine south to Georgia and as far west as Kentucky. It is found in environments which other species would find unsuitable for growth, such as acidic, sandy, and low-nutrient soils.
Pinus serotina, the pond pine, black bark pine, bay pine,marsh pine, or pocosin pine, is a pine tree found along the Southeastern portion of the Atlantic coastal plain of the United States, from southern New Jersey south to Florida and west to southern Alabama. Pond pine distribution may be starting to spread west towards Mississippi and Tennessee.
Pinus densiflora, also called the Japanese red pine, the Japanese pine, or Korean red pine, is a species of pine tree native to East Asia. In China it is known as 赤松.
Coulter pine, or big-cone pine, is a native of the coastal mountains of Southern California in the United States and northern Baja California in Mexico. Isolated groves are found as far north as Clearlake, California on the flanks of Mt. Konocti and Black Diamond Mines Regional Preserve. It is named after Thomas Coulter, an Irish botanist and physician. The Coulter pine produces the heaviest cone of any pine tree, up to 5 kg (11 lb) and among conifers is exceeded only by the cones of Araucaria bidwillii.
Pinus ponderosa, commonly known as the ponderosa pine, bull pine, blackjack pine, western yellow-pine, or filipinus pine is a very large pine tree species of variable habitat native to mountainous regions of western North America. It is the most widely distributed pine species in North America.
Pinus koraiensis is a species of pine known commonly as the Korean pine. It is a relic species of the Tertiary, identified as a rare tree species by United Nations. It is native to eastern Asia: Korea, northeastern China, Mongolia, the temperate rainforests of the Russian Far East, and central Japan. In the north of its range, it grows at moderate elevations, typically 600 to 900 metres, whereas further south, it is a mountain tree, growing at 2,000 to 2,600 m elevation in Japan. Other common names include Chinese pinenut. The ancient woodland of P. koraiensis on the earth is about 50 million hectares, and China has about 30 million hectares, accounting for 60%. It is a second-class national key protected plant in China. P. koraiensis is a tree species with high economic and ecological value. The official name in Chinese is "红松 hóng sōng/red pine", because almost every part of it is related to red.
Podocarpus macrophyllus is a conifer in the genus Podocarpus, family Podocarpaceae. It is the northernmost species of the genus, native to southern Japan and southern and eastern China.

It bears plentiful, fragrant, white flowers and edible red to yellow fruit of about 1 cm diameter.
A wilt disease is any number of diseases that affect the vascular system of plants. Attacks by fungi, bacteria, and nematodes can cause rapid killing of plants, large tree branches or even entire trees.
