Use of the word "Seedling"

For me, my experience with "seedlings" comes from hybridizing irises.
Anything I've grown from seed, is a seedling... even if it is 15 years old
now and a massive clump of rhizomes in my garden. To other hybridizers (&
iris enthusiasts in general) the name "seedling" implies that I haven't
named, registered, or introduced this iris yet.
