groupcedar

Groupcedar is an informal, non-taxonomic designation used in horticulture and plant discussion to describe a cedar-like group of evergreen conifers that share similar growth forms and aromatic wood. It is not recognized as a formal taxon in current botanical classification, and different sources vary in which species or genera are included.

In common usage, the term can encompass true cedars of Cedrus and several other genera that are commonly referred to as cedars in the nursery trade, such as Calocedrus and Libocedrus, as well as other cedar-shaped conifers resembling Cedrus. Because there is no universal definition, the boundaries of the group are fluid and debated among botanists and gardeners.

Groups designated as groupcedar typically include trees that are evergreen conifers with resinous wood and a range of forms from tall, narrow spires to broad pyramids. Foliage can be needle-like in clusters or scale-like, depending on lineage, and cones are a common feature among members.

Distribution and habitat for groupcedar members span temperate regions of Europe, Asia, and North America, with habitats from montane forests to dry ridges. Several species are long-lived and drought-tolerant once established.

Cultivation and use: In landscaping, groupcedar taxa are valued for ornamental appeal, windbreak potential, and timber. They typically require well-drained soil, full sun, and ample space; cold tolerance is common, though some species prefer cooler or moister microclimates. Pests and diseases vary by species but can include scale insects and fungal pathogens.

Taxonomic status: Because it is an informal grouping, the term is used inconsistently and should not be treated as a formal rank. For rigorous classification, botanists refer to the individual genera and species (Cedrus, Calocedrus, Libocedrus, and related conifers).

Related terms include true cedars, false cedars, and various conifers in the same broad group.
