These two plant species offer native insects and birds hardly any nutritional value or habitat. Considering the enormous insect decline over the years, this choice is unfortunate. Therefore, alternatives are promoted.
...when I look at my mother-in-law's 40-year-old thuja and see what lives, crawls, and flutters inside, I just ask completely ignorantly: REALLYY???;) :p
But I understand the approach, nonetheless I have to say better cherry laurel and thuja than 40m stone gabions or double rod mat fences with woven-in privacy screens. Everyone has to decide for themselves. And whether cemetery plant or not... is a matter of taste. Around here at the cemeteries there are stone walls or hornbeam hedges. :p
