This is a slow growing deciduous tree that has downward arching- weeping branches making it an interesting specimen. It has a dull green colour during the summer and turns a yellow colour during the autumn. As the tree loses its leaves the branches are exposed presenting a strong appearance during the winter months. It is a good lawn or ornamental tree along streets, in parks and gardens.

Description and Growing Information
Flowering Period
General Description
The leaves are a dull green during the summer, but turn yellow during the autumn and the bark and twigs are smooth and are a greenish-brown colour. The tree has a very distinct pendulous form very similar to Morus alba 'Pendula'.
It can be planted in urban areas, including parks, along residential streets and as a garden or landscape specimen. Its colour and flat-topped shape makes it a prominent landscape feature in autumn, the barren branches make the tree even more dramatic in winter.
Ulmus glabra 'Pendula' does well in most soils and can grow in high alkaline soils of a pH of 8 to low acidic soils of 5.5. It is tolerant of partial shade but prefers full sun.
The tree has a flat-top with horizontal branches fanning outward that droop down.
ID Characteristic
The tree branches horizontally at the top producing a flat form, with the branches hanging down at the edges creating an umbrella effect. The leaves are very rough adaxial and hairy abaxial. The bark of the tree is smooth and is a greenish-brown colour.
It can suffer from Dutch elm disease, and wet-wood, but can also be affected by Elm yellows, also known as Phloem Necrosis, which slowly kills the tree.
Horticultural origin.
Bark/Stem Description
When the bark is young, it is smooth and has a greenish-brown colour to it with pale grey lenticels that form horizontally along the branches and twigs. As the tree ages, the older branches form red coloured fissures vertically down the bark.
Flower/Leaf Bud Description

Flower Description
The flowers appear in the early spring before the leaves emerge and are a purple red colour, they occur in clusters along the stems of the tree.
Fruit Description
Produces indehiscent fruit called a samara which are 5 mm wide. The samara has an oval shape that is tipped at one end and is a dull yellow to white colour they occur in clusters or bundles (umbels) all over the tree.
Colour Description
