1540s, "to plant in" (abstractly, of ideas, emotions, etc.), from French implanter "to insert, engraft" (alongside Old French emplanter "to plant"), literally "plant in," from assimilated form of in- "into, in, on, upon" (from PIE root *en "in") + planter "to plant" (see plant (n.)). Meaning "surgically implant (something) in the body" is from 1886, originally of teeth. Implanted is attested earlier, from early 15c., probably based on Medieval Latin implantus. Related: Implanting.
mid-15c., from Late Latin transplantare "plant again in a different place," from Latin trans "across, beyond" (see trans-) + plantare "to plant" (see plant (n.)).

type of bulbous flowering plant, 1540s, from Latin narcissus, from Greek narkissos, a plant name, not the modern narcissus, possibly a type of iris or lily, associated with Greek narkē "numbness" (see narcotic (n.)) because of the sedative effect of the alkaloids in the plant, but Beekes considers this folk-etymology and writes that "The suffix clearly points to a Pre-Greek word."
