Her favorite childhood berry was the mulberry - a berry completely unknown to me. Out of curiosity, I tried getting mulberries - but since those grow on trees which only start bearing fruit after 10 years of growth (!!!) - those can't be produced at a commercially viable price point.

It wasn't until years later, that I found a mulberry tree in an old cloister garden, of a cloister that specialized in preserving old strands of plants that were no longer being commercially grown.

They are really tasty! If they were actually available, I could easily see them become just as popular as other berries.
