Technically speaking the "first generation" sometimes referred to as f1, is the first set of progeny from a particular plant. If the parent plant is a species plant such as H. pycnophylla, then the f1 would be a hybrid. An example of a pycnophylla f1 would be Gilt by Association or Frisian Pride.

Fire Island is an f1 plant from H. longipes f. hypoglauca. So it is the first generation of a species plant.

...my mouth is hanging slightly ajar and I look like the lights are on, but nobody's home......but I *think* might have actually understood that. lol

So, the person was right, Fire Island is First Generation. Thank you so much Steve, I appreciate you making the effort to sort that out for me.

your child.. is the first generation of you and your husband ... F1 ... a defined gene pool ...

her child would be the second generation.. or F2 .. but having the added gene pool of the spouse in that cross ...

it is a direct analogy ... nothing mysterious in it all.. except for the F designation ... which leads me to wonder... why F? ... going to spend the day mulling that one ...

the best example of this.. was eric smith crossing a late RE- blooming giant Elegans.. with and the small tardianna... in hope of creating the first small blues ... his F1's .. [the ones with all the british bird names]

as those seedlings developed.. he took them.. and crossed them back onto each other.. going for smaller and bluer.. creating his F2's ...

then herb benedict.. took a couple these plants out to F5 ... the fifth generation.. linked to the original crosses ...

its just a way of tracking ..noting.. and talking about the generations ....

ps: if you take an F1 ... and keep crossing it back onto itself... you can bring out the recessive genes of either parent ... trying .. in this example.. to make it either smaller or bluer ... what i always found interesting.. is that some bloom early like the elegans.. while others bloom late like tardiana ...

Fascinating. Definitely puts it all in perspective.

I thought I would google the 'F' question and then I realized that if you don't know, then I probably wouldn't be able to find the answer! :)

Thanks for the explanation.

Per Wiki...

"F1 stands for Filial 1, the first filial generation seeds/plants or animal offspring..."

I did not know that.

i figured it meant Family.... or the latin equivalent.. as the junky notes ...

As a retiree, I am the first generation of my living family, have a son, 2nd generation, and a wonderful grandson, now 10 yrs old, 3rd generation. OK, got it!
