flower seed saving
I have read through quite a few posts & haven't found an answer so hope one of you might be able to help.
Does the book Seed to Seed guide in flower seed collecting? If not, is there another book specifically addressing planning for saving flower seeds?
If a flower seed isn't labeled hybrid, can one assume it is open pollinated?
Are there spacing requirements for specific flowers to avoid cross pollination or is it that flowers do not cross pollinate as do many vegetables? Common flowers that would have several different in the same garden would be zinnia & sunflowers.
I am planning my garden & if there are spacing considerations, it is good to know now rather than in the fall when I am collecting seeds. :-)
Thanks to all for your guidance!!
