Fraxinus excelsior, known as the ash, or European ash or common ash to distinguish it from other types of ash, is a flowering plant species in the olive family Oleaceae. It is native throughout mainland Europe east to the Caucasus and Alborz mountains, and Great Britain and Ireland, the latter determining its western boundary. The northernmost location is in the Trondheimsfjord region of Norway. The species is widely cultivated and reportedly naturalised in New Zealand and in scattered locales in the United States and Canada.
Fraxinus angustifolia, the narrow-leaved ash, is a species of Fraxinus native to Central Europe and Southern Europe, Northwest Africa, and Southwest Asia.
The Field Elm cultivar Ulmus minor 'Viminalis Marginata', a variegated form of Ulmus minor 'Viminalis', was first listed as Ulmus campestris var. viminalis marginataHort. by Kirchner in 1864. Both Van Houtte and Späth marketed an U. campestris viminalis marginata in the late 19th century.
The American Elm cultivar Ulmus americana 'Nigricans'Dieck was cloned from a selection made from seedlings raised by the Zöschener Baumschule, Zöschen, Germany, and listed by Georg Dieck with a brief description in Haupt-catalog der Obst- und gehölzbaumschulen des ritterguts Zöschen bei Merseburg, 1885.
The elm cultivar Ulmus 'Crispa Aurea' was first mentioned by Schelle & Beissner in 1903, as Ulmus montana crispa aurea.
The Wych Elm cultivar Ulmus glabra 'Latifolia Aurea' was listed by Schelle in Beissner et al, Handbuch der Laubholz-Benennung (1903), as Ulmus glabraMillerlatifolia aurea, but without description. In the Netherlands in the late 19th and early 20th centuries, however, Ulmus montana latifolia aurea was a synonym of the wych cultivar 'Lutescens', and Green reclassified Schelle's 'Latifolia aurea' as a form of U. glabraHudson.
The European White Elm cultivar Ulmus laevis 'Aureovariegata', a yellow-variegated form, may have been the tree first listed, without description, in Hortus Regius Monacensis (1829) as Ulmus effusa variegata, grown at the Munich Botanic Garden. An Ulmus effusa fol. variegatis (Hort.) was first described c.1890 by the Späth nursery of Berlin, which distributed the tree in the late 19th century. The name U. effusa f. aureovariegata appeared in Beissner and Schelle's Handbuch der Laubholz-Benennung, 1903, without description.
The European White Elm cultivar Ulmus laevis 'Punctata' was mentioned in 1873, 1889, and later in 1903 as U. effusa f. punctata, but without description.
The American elm cultivar Ulmus americana 'Pendula' was originally listed by William Aiton in Hort. Kew, 1: 320, 1789, as U. americana var. pendula, cloned in England in 1752 by James Gordon. From the 1880s the Späth nursery of Berlin supplied a cultivar at first listed as Ulmus fulva (Michx.) pendulaHort., which in their 1899 catalogue was queried as a possible variety of U. americana, and which thereafter appeared in their early 20th-century catalogues as U. americana pendula. The Scampston Elm, Ulmus × hollandica 'Scampstoniensis', in cultivation on both sides of the Atlantic in the 19th and 20th centuries, was occasionally referred to as 'American Weeping Elm' or Ulmus americana pendula. This cultivar, however, was distinguished by Späth from his Ulmus americana pendula.
The elm cultivar Ulmus 'Nemoralis' was listed by Schelle in Beissner et al. (1903), as U. campestris f. nemoralisHort. Considered "possibly U. carpinifolia " by Green.
The Field Elm cultivar Ulmus minor 'Pendula' was said to have been raised in Belgium in 1863. It was listed as Ulmus sativa pendula by C. de Vos in 1887, and by Boom in 1959 as a cultivar.
The Wych Elm cultivar Ulmus glabra 'Pendula Variegata' was first described in 1850, and later by J. F. Wood in The Midland Florist and Suburban Horticulturist (1851) as U. montana pendula variegata, the 'broad-leaved variegated weeping mountain elm', and was said by him to have originated in and been distributed by the Pontey nursery of Kirkheaton, Huddersfield, Yorkshire. It was listed by Hartwig & Rümpler in Illustrirtes Gehölzbuch (1875) as Ulmus montana (:glabra) var. pendula variegataHort.
Weeping trees are trees characterized by soft, limp twigs. This characterization may lead to a bent crown and pendulous branches that can cascade to the ground. While weepyness occurs in nature, most weeping trees are cultivars. Because of their shape, weeping trees are popular in landscaping; generally they need a lot of space and are solitary so that their effect is more pronounced. There are over a hundred different types of weeping trees. Some trees, such as the cherry, have a variety of weeping cultivars. There are currently around 550 weeping cultivars in 75 different genera, although many have now disappeared from cultivation.
Ulmus × hollandica 'Wentworthii Pendula', commonly known as the Wentworth Elm or Wentworth Weeping Elm, is a cultivar with a distinctive weeping habit that appears to have been introduced to cultivation towards the end of the 19th century. The tree is not mentioned in either Elwes and Henry's or Bean's classic works on British trees. The earliest known references are Dutch and German, the first by de Vos in Handboek tot de praktische kennis der voornaamste boomen (1890). At about the same time, the tree was offered for sale by the Späth nursery of Berlin as Ulmus Wentworthi pendulaHort.. The 'Hort.' in Späth's 1890 catalogue, without his customary label "new", confirms that the tree was by then in nurseries as a horticultural elm. De Vos, writing in 1889, states that the Supplement to Volume 1 includes entries announced since the main volume in 1887, putting the date of introduction between 1887 and 1889.
Acer negundo 'Pendulum', or weeping boxelder maple, is a weeping tree and a cultivar of Acer negundo, the boxelder maple. It was first described by Fritz Kurt Alexander von Schwerin in 1896. No trees are known to survive of this cultivar.
Betula pubescens 'Pendula', or Weeping Downy Birch, is a weeping tree and a cultivar of Betula pubescens, the Downy Birch. It was first described by Schelle in 1903. No trees are known to survive of this cultivar.
Morchella palazonii is a species of morel found in Spain.
The Field Elm cultivar Ulmus minor 'Cucullata Variegata', a variegated form of U. minor 'Cucullata', was listed by C. de Vos, in 1867, as U. americana cucullata folia variegata and by Schelle in Beissner Handbuch der Laubholz-Benennung, 82 (1903) as U. campestris concavifolia cucullata variegataHort, without description.
The field elm cultivar Ulmus minor'Viminalis Pendula', a weeping form of U. minor 'Viminalis', was first listed c.1890 as Ulmus antarctica pendulaHort., and briefly described, by the Späth nursery of Berlin, which distributed it from the late 19th century. On the continent it was also known as U. campestris antarctica pendula. Maxwell T. Masters in the Journal of the Royal Horticultural Society (1891) listed it as U. viminalis pendula.
The elm cultivar Ulmus 'Crispa Pendula', the weeping fernleaf elm, was listed in the Gardeners' Chronicle & New Horticulturist (1873) as Ulmus crispa pendula, a variety of 'Crispa', itself described as "of the U. montana type".
