    According to Wikipedia, F1 hybrid is:

    '[...] seeds/plants or animal offspring resulting from a cross mating of distinctly different parental types. The term is sometimes written with a subscript, as F1 hybrid. The offspring of distinctly different parental types produce a new, uniform variety with specific characteristics from either or both parents'

    If this definition is correct, then Cephalotus follicularis cv. 'Eden Black' x 'Eden Black' does not appear to match this.

    Here's a slap-happy series of shots from a pair of centrifuge tubes this morning . . .

    Cephalotus follicularis cv. "Eden Black" F1

    Also, the term "hybrid" is reserved for the crossing of two plants NOT of the same species, so any crosses involving selections/cultivars of C. follicularis cannot be described as hybrids, since the genus is monospecific.

    very nice david! great to see....

    F0 is considered the source.
    F1 is considered the offspring of F0
    F2 is considered the offspring of F1, etc etc etc....

    the F label is independent of hybridic origin.

    Would Cephalotus follicularis "Eden Black" selfed seeds be more accurate a description? To my mind an F1 is a crossing between different parents.
