From Zelda Dungeon Wiki
Bipin is an expert arborist and knows everything about growing Gasha Trees. He is obviously a descendant of Pippin, a man of roughly the same profession and resemblance who lives in Lynna Village in the Past.Son. Blossom, Bipin's wife, gives Link the honor of being able to suggest a name for the newborn baby, which Bipin will like no matter what is chosen. Afterwards, Bipin gives Link a Gasha Seed. Thoughout his quest, Link can go to Bipin for much advice on planting Gasha Seeds.
