Robinia pseudoacacia 'Karolina Zamoyska'
The variety has lemon yellow or light green yellow variegated leaves. Th eleaves become darker and the variegation lightens up and finally becomes white over time. Interesting is the fact that the leaves change their colors best when the plant is cultivated in shadow or partial shadow areas. Completely frost hardy; its growth does not diverge from the one of the species.Tree bred in Nurseries in Podzamcze at the time the Nurseries were managed by Feliks Rożyński. It was in the nursery’s offer between 1903 and 1913. The variety was named in honor of then 7-year old Karolina Franciszka Józefa Zamoyska, daughter of the owner of the nurseries.
After World War II it disapearred without a trace; no pieces of this tree were known. Only in 1981 in a park nearby Hoser nurseries in Pruszków nearby Warsaw, Wiesław Gawryś from the Botanical Garden in Powsin, found a tree with atypical cream variegated leaves. The tree was reproduced in 2006 by Szmit Nursrey and again introduced to cultication. After observation and comparison with available archive materials the tree was identified as 'Karolina Zamoyska'.
'Karolina Zamoyska' shall be paid attention to due to interesting color of leaves and, most of all, due to its interesting history and domestic origin.
