Cosmos orange flowers & yellow flowers

four(9B (near 9a))May 12, 2014

Seeds that I was given were labeled "Orange Cosmos".
Flowering started recently.
Some plants have all yellow flowers, other plants have all orange.

1) Will subsequent flowers on these plants necessarily be of the original color?

2) Will subsequent Cosmos plants grown from seeds of a flower of a given color necessarily produce flowers of that color?

a gift from someones garden??? .. or bought in a seed pack ...

second generation seeds of foo foo colors.. due to genetic variances.. will not necessarily be true to color ... of momma ...

flower color is not going to change on a given plant.. as more flowers open ... old flowers might fade.. sometimes to a different color ... but that doesnt sound like what you are talkign about ...

to insure a specific color .. you usually have to buy the seeds new.. every year ...

i think of cosmos as the pink, red and white family .... so i would call orange.. foo foo ... its a very scientific term.. lol ..

True that I wasn't, but only because I was unaware that the color changing
that I thought that I was seeing (now am sure of it)
would be in existing flowers.
So, the information is more than relevant,
it is spot on (as Brits say).

I see. Hybridized, then.

> will not necessarily be true to color

Not also the seeds from first generation hybrids?

There are two different types of cosmos. The white, pink, purple varieties are Cosmos bipinnatus and the yellow, orange varieties are mostly Cosmos sulphurous. I may have butchered the spelling. Anyway, neither is foo foo, just different.

when i say foo foo.. in this setting ...

i am comparing species traits ... which would be replicated thru seed gathering ...

as compared to genetics taken to the ultimate end product with a bizarre extreme flower or some such .. which either end up sterile ... or do not come true from seed ...

either way.. you need to rebuy the seed ...

docmom... i was to lazy to research out this persons plant.. i figured.. as soon as i said they favor one color spectrum.. that i was probably stepping in it.. lol .. but some things should be left to the poster ...

OP .. you might get an ID here or in the name that plant forum.. if you could figure out how to post pix ...

I wrote nothing that requests ID.
It is an element that you are tacking on.
Fine with me, just don't write as though it were my thing.

My C. sulphureus 'Cosmic Orange' come true every year from saved seeds, but then I didn't grow any other Cosmo at the same time. I love that they are shorter and don't flop like C. bipinnatus.

I have some orange cosmos (Diablo). The seeds I have saved all produce orange flowers.

Maybe you have seeds of bright lights which includes orange and yellow.

Thanks for all of the inputs.

These plants were prolific, first in pots then also in ground.
"Were", because all (probably 30) soon died.
Same for those that I gave to neighbor.
