The mistletoe I found in Peoples Park and publicised in the Halifax Courier has prompted three other reports in Calderdale:
In a private garden at Southowrham, started “by rubbing some berries into the apple tree bark” by a lady gardener about 15 years ago. Never has berries.
Again in a garden at Brighouse on apple . Just got a message from a man I couldn’t contact back. “There about 20 years and reported in the Courier”.
Some memories from about 50 years back of gathering it for Christmas in more than one place in Ovenden, including from a holly tree.
The one Colin D found, plus the two I found (Hebden Bridge and Peoples Park) brings the total to 6 sites. Still a rare plant, though. The icing on the cake would be to find it with berries.
