In Greek mythology, Cyparissus or Kyparissos was a boy beloved by Apollo or in some versions by other deities. In the best-known version of the story, the favorite companion of Cyparissus was a tamed stag, which he accidentally killed with his hunting javelin as it lay sleeping in the woods. The boy's grief was such that it transformed him into a cypress tree, a classical symbol of mourning. The myth is thus aetiological in explaining the relation of the tree to its cultural significance. The subject is mainly known from Hellenized Latin literature and frescoes from Pompeii. No Greek hero cult devoted to Cyparissus has been identified.
The Leyland cypress, Cupressus × leylandii, X Cuprocyparis leylandii or X Cupressocyparis leylandii, often referred to simply as leylandii, is a fast-growing coniferous evergreen tree much used in horticulture, primarily for hedges and screens. Even on sites of relatively poor culture, plants have been known to grow to heights of 15 metres (49 ft) in 16 years. Their rapid, thick growth means they are sometimes used to achieve privacy, but such use can result in disputes with neighbours whose own property becomes overshadowed. The tree is a hybrid of Monterey cypress and Nootka cypress. It is almost always sterile, and is propagated mainly by cuttings.
Cupressus sempervirens, the Mediterranean cypress, is a species of cypress native to the eastern Mediterranean region and Iran. Cupressus sempervirens is a seeded vascular plant, meaning that it contains both xylem and phloem. Since it is a seeded plant, it uses seeds to reproduce. It has many uses that can contribute to medicine and other things that are beneficial, whether that be the seeds that it produces or the oil that comes from the leaves. It is well adapted to the conditions and the environment that it lives in. Cupressus sempervirens is widely present in culture, most notably in Iran, where it is both a sacred tree and is a metaphor for "the graceful figure of the beloved".
A plant canker is a small area of dead tissue, which grows slowly, often over years. Some cankers are of only minor consequence, but others are ultimately lethal and therefore can have major economic implications for agriculture and horticulture. Their causes include a wide range of organisms as fungi, bacteria, mycoplasmas and viruses. The majority of canker-causing organisms are bound to a unique host species or genus, but a few will attack other plants. Weather and animal damage can also cause stress to the plant resulting in cankers. Other causes of cankers is pruning when the bark is wet or using un-sterilized tools.
Cupressus arizonica, the Arizona cypress, is a North American species of tree in the cypress family Cupressaceae, native to the southwestern United States and Mexico. Populations may be scattered rather than in large, dense stands.
Dieback may refer to a number of plant problems and diseases including:
Isoparce cupressi, the baldcypress sphinx or cypress sphinx, is a moth of the family Sphingidae.
Agaricus pattersoniae is an edible species of mushroom. It is found in the United States, where it associates with cypress trees. It has been proposed for inclusion in the IUCN Red List of Threatened Species.
Lepteutypa is a genus of plant pathogens in the family Amphisphaeriaceae. First described by the Austrian mycologist Franz Petrak in 1923, the genus contains 10 species according to a 2008 estimate. It was increased to 15 in 2020.
Cupressus arizonica var. glabra, known as the Arizona smooth bark cypress or smooth Arizona cypress, is a conifer native to the American Southwest, with a range stretching over the canyons and slopes in a somewhat wide vicinity around Sedona, Arizona. It was first described by George Bishop Sudworth in 1910.
Cinara cupressi, the cypress aphid, is a brownish soft-bodied aphid. It sucks sap from twigs of conifers, and can cause damage to the tree, ranging from discoloring of the affected twig to the death of the tree. This insect appears to have originated in the Middle East and has been increasing its range and is considered to be an invasive species in Africa and Europe. It has been included in the List of the world's 100 worst invasive species.
Seiridium is a genus of plant pathogens in the family Sporocadaceae.
Cinara, the conifer aphids or giant conifer aphids, is a genus of aphids in the family Aphididae. They are widespread in the Northern Hemisphere.
Neozygites remaudierei is a microscopic fungus in the order Entomophthorales, which affects aphids, particularly Myzocallis coryli.
Neozygites slavi is a microscopic fungus in the order Entomophthorales, which affects aphids, particularly Slavum esfandiarii.
Taxodiomyia is a genus of cypress gall midges, insects in the family Cecidomyiidae. There are at least 3 described species in Taxodiomyia.
Phloeosinus cupressi, the cypress bark beetle, is a species of crenulate bark beetle in the family Curculionidae. It is found in North America.
Cypress canker is a disease affecting Cupressus species, caused by one of several species of fungus in the genus Seiridium. Infection causes die-back of twigs and branches in susceptible cypress trees, with rapidly increasing amounts of damage and the death of the tree.
Seiridium cardinale is a species of fungus within the genus of Seiridium, in the Sporocadaceae family.
Phloeosinus aubei is a species of bark beetle in the family Curculionidae. It is commonly known as the cedar bark beetle, eastern juniper bark beetle, or small cypress bark beetle.
