I thought at first that they were silverberries but @david.w.francis told me they weren't but were Japanese cornel (Cornus officinalis). I sometimes (or often?) make similar mistakes and each time people kindly give me a chance to make corrections!
Writing about plants gives me joy and connecting with people through plants also brings me happiness!
Original post, which is wrong:
Bright red berries hanging from tree branches with no leaves stood out. These are silverberries (Elaeagnus). They look delicious but are not so tasty as they look (according to those who've actually eaten them). I wanted to identify the species of these Elaeagnus trees but in vain. Elaeagnus comprises 50 to 90 species!
