I am interested in ripe mistletoe berries if someone has any to spare.
Hoy,
I have mistletoe growing on Malus and Sorbus for about 20 years. After several tries with berries from x-mas mistletoes I finally succeeded in two plants on a Sorbus tree. Luckily it was a female and a male plant, and after about 6 years I got the first berries. I tried sowing these on different tree species, but they only succeeded on Malus and Sorbus. Fresh berries from my own plants germinates readily, but leaves are first present in 2-3 years.
They are fully hardy here, with temperatures down to -22
oC
If your are interested I can send you some berries in March when they are ripe.
