Tree Information x

Identifier: WKR/1228
Tree Type: Single
Registered By: Smillie, M.J.
Registration Category: Notable tree/s – Local interest
General Notes:
The last remaining of three walnut trees once located at this old historic site. See the former large Japanese walnut WKR/0752 that was included as number 28 in Burstall and Sale’s 'Great Trees of New Zealand' (Smillie, 2014).

This specimen is often referred to as the former Japanese walnut but a 2015 identification confirmed the tree to most likely be the hybrid between J. regia and J. mandshurica, generally known as Juglans ×sinensis (pers. comm, Wilcox, M. 6 April 2015).
