On November 1st, 2009, the first 25 trees in the Luthergarten were adopted. Church Executive Peter Kollmar (citing the selected Bible verse) planted a honey locust tree on behalf of the Evangelical Lutheran Church in Brunswick, Germany.
On April 26th, 2012, a honey locust tree was planted as partner tree for the Evangelical Lutheran Church in Brunswick in front of the Federal Office for Radiation Protection in Brunswick, Germany. The tree planting took place at 11:55 – “five to twelve,” which is a phrase indicating the very last minute – in order to raise awareness about the dangers of nuclear power. According to church official Thomas Hofer of Wolfenbüttel, the church made a conscious decision for April 26th and the Office of Radiation Protection. On this day the 26th anniversary of the reactor catastrophe of Chernobyl was remembered.
