Rowan some countries, but "Sorbus domestica", for example, has largely vanished from Britain, where it was traditionally appreciated. Natural hybrids, often including "Sorbus aucuparia" and the whitebeam, "Sorbus aria", give rise to many endemic variants in the UK. The traditional names of the rowan are those applied to the species "Sorbus aucuparia", "Sorbus torminalis" (wild service-tree), and "Sorbus domestica" (true service-tree). The Latin name "sorbus" was borrowed into Old English as "syrfe". The name "service-tree" for "Sorbus domestica" is derived from that name by folk etymology.

Insecticidal soap at higher concentrations or at temperatures above 32 °C (90 °F). Plant injury may not be apparent until two days after application. Some plant species are particularly sensitive to soap sprays. Highly sensitive plants include: horse chestnut, Japanese maple ("Acer"), "Sorbus aucuparia" (mountain ash), Cherimoya fruit, "Lamprocapnos" (bleeding heart), and sweet pea. Other sensitive plants are, for example: "Portulaca", some tomato varieties, "Crataegus" (hawthorn), cherries, plum, "Adiantum" (maidenhair fern), "Euphorbia milii" (crown of thorns), "Lantana camara", "Tropaeolum" (nasturtium), "Gardenia jasminoides", "Lilium longiflorum" (Easter lily). Conifers under (drought) stress or with tender new growth are sensitive as well. Damage may occur
