Just checked about the berries and this is what I found on wikipedia.Pyracantha berries are mildly poisonous as their seeds contain cyanogenic glycosides (as do apples, plums, cherries, and almonds[4]) and can cause mild gastro-intestinal problems when eaten raw in large quantities;[4][5][6] they are edible only when crushed and washed under running water. They have been made into jelly.[7]👍
... confusing... I think Pyrachantha in great quantity give poison... remember... the poison is not a particular subtance... but the dosage...
Yes the berries you showed are also known as rose hip and they are definitely edible. Thankyou for your posts it's been interesting looking up about the plants and learning about their fruits.
