Flowering Ash: A Small, Decorative and Easy-to-Grow Tree. Le Quotidien du Jardin No. 311

NewsJardinTV, the channel that shares your passion for plants, gardens, botany, nature, and gardening, offers you issue 311 of its show "Le Quotidien du Jardin" (The Garden Daily) produced by Nicole and Patrick Mioulane. Anthony Vallette asks us the following question: Could you tell us about Fraxinus ornus in an upcoming episode? Fraxinus ornus is the botanical name for the flowering ash. The genus Fraxinus (Carl von Linné 1753, 63 species, 82 taxa) is part of the Oleaceae family, which takes its name from the genus Olea (olive tree), a family that includes, among others: Forsythia, Jasminum (jasmine), Ligustrum (privet), Osmanthus, and Syringa (lilac). Fraxinus ornus was described and named in 1753 by Carl von Linné. This is the flowering ash, which also has common names: manna ash, orne ash, or elm ash. It is a species native to southern Europe, indigenous to France in the Alpes-Maritimes and Corsica, but found as far away as southwest Asia. It grows from sea level to 1,500 m above sea level. Fraxinus ornus is a deciduous tree with a rounded silhouette and a bushy crown, averaging 7 to 10 m tall, making it an attractive species for a small garden. However, there are old specimens exceeding 20 m (lifespan, however, rarely exceeds 100 years). The trunk, with smooth, grayish bark, is relatively short and straight and does not exceed 1 m in diameter. The sinuous, slightly forked branches point upward. The brown buds, dusted with an ash-grey velvet, open onto opposite, imparipinnate leaves, 15 to 25 cm long, composed of 5 to 9 leaflets, 5 to 10 cm long, petiolate, oval to lanceolate, wavy, finely toothed, whitish, and slightly pubescent on the underside of the midrib. The leaves take on a pretty autumn color ranging from golden yellow to purplish red or even purplish. Flowering often appears at the same time as the leaves and continues until May-June. The terminal or axillary panicles, 10 to 20 cm long, are dense, composed of pleasantly fragrant, creamy-white flowers with 4 linear petals. Flowering is said to be androdioecious, the trees bearing hermaphroditic flowers, but sometimes only the male organs (stamens) are functional. Entomogamous pollination (bees and beetles) produces fruiting bodies in hanging clusters of samaras (dry fruits accompanied by a membranous wing), oblong to lanceolate, about 3 cm long, green, then brown, which persist on the tree throughout the winter. There are two valid subspecies: Fraxinus ornus subsp. cilicica, which was first described as a species in 1907 by the German botanist and pharmacist Alexander von Lingelsheim (1874–1937). It was then reduced to subspecies status in 1961 by the Turkish botanist Faik Yaltirik (1930–2016). It is a form specific to the Taurus Mountains located in southern Turkey. Fraxinus ornus subsp. ornus is found in Eastern Europe, mainly in Hungary. The cultivar 'Mecsek', also known as the dwarf flowering ash, is a compact, rounded form, usually grafted onto Fraxinus exelsior to form a stem. The plant grows to a maximum height of 3 m and a width of 2 m, making it suitable for growing in containers. The flowering ash is an excellent shade tree that is sometimes planted in rows in cities. With good hardiness (-15°C), the flowering ash thrives in cool (but drought-resistant) soils rich in deep, well-drained organic matter, even calcareous soils, although it prefers soils with a neutral pH. It should be planted in full sun, sheltered from strong winds. Unlike the common ash (Fraxinus exelsior), which has been threatened since 2008 by the fungal disease commonly known as chalara dieback, caused by the fungus Hymenoscyphus pseudoalbidus, and which causes fatal necrotic lesions, the flowering ash does not appear to be a natural host for the pathogen. A sugar (mannitol), which flows after a cut is made in the bark, is extracted from the sap of the flowering ash, mainly in Sicily. In the Middle Ages, this syrup was compared to manna (the food of the Hebrews during their exodus into the desert), hence its nickname "manna ash." The crystallized sap takes on a yellow color and has a sweet and sour taste. It is used as a sweetener, laxative, and digestive aid. Thank you for watching this daily program. We hope you enjoyed this short video interlude. The entire NewsJardinTV team wishes you a wonderful evening and looks forward to seeing you tomorrow at 7 p.m. for a new show: "LE QUOTIDIEN DU JARDIN." It's on NewsJardinTV and nowhere else! In the next show, Patrick will answer this question: How to care for jasmine?
