Description
Sophora japonica – Japanese pagoda tree
Quality: 1/1 P 30-50
Short description: The Japanese pagoda tree is a broad-crowned, summer-flowering deciduous tree with a distinctive character. In July and August—when hardly any other tree is in bloom—creamy white, lightly fragrant flower panicles open, attracting large numbers of bees and bumblebees. The finely pinnate foliage casts a light, airy shade. As a long-lived urban tree, it is still planted far too rarely in southern Germany.
Climatic characteristics & site conditions: The pagoda tree is exceptionally tolerant of heat and drought—an attribute that is becoming ever more valuable in view of climate change in the Upper Rhine Plain, the Stuttgart Basin, or Franconia. It prefers warm, sunny sites and well-drained soils. Hardy down to approx. −20 °C; young plants can be sensitive to frost in harsh locations. It is less suitable for higher elevations above 700 m in the Black Forest or the Swabian Jura.
Advantages: Summer flowering when hardly any other trees bloom, excellent heat and drought tolerance, resilient in urban climates, long-lived, bee-friendly, attractive foliage.
Disadvantages: Not native, frost-sensitive when young, unsuitable for cool high-elevation sites, pods and fallen flowers may require more intensive clean-up, slow growth in the first few years.
