Trees for Alkaline Soils
TREE-DRAINING, and warming faster than most other soils in spring, alkaline soils suit a wide range of ornamental trees, some of them very popular and reliable flowering trees. Many hail from regions enjoying warm summers and so appreciate sun and warmth to help ripen their wood and promote flowering.
JUDAS TREE
Occasionally multi-stemmed, this more often single-stemmed, spreading tree has heart-shaped blue-green leaves. Rosy lilac pea-flowers emerge in spring and are followed by flattened red seed pods. Bodnant' is a form with deep purple flowers.
ORIENTAL THORN
This slow-growing ornamental thorn tree will eventually develop a dense, rounded crown clothed in deeply lobed, dark green leaves. Clusters of pretty white blossoms emerge in late spring, and its large, downy red fruits are produced in autumn.
PINK SIRIS, SILK TREE
As a young tree, Pink Sins is more broad than tall, with spreading branches and finely divided, fern-like leaves. Its clusters of fluffy, pink-stamened flowers are produced in late summer and autumn. A. julibrissin 'Rosea' is a more hardy selection.
