CHIEF HEMATITE is a red-brown, produced by a combination of carotene and
anthocyanadin pigments.  WHITE LIGHTNING apparently carries at least one
type of recessive white gene as well as the dominant anthocyanadin
inhibitor.  Mix up the genes and you can get the inhibitor from WHITE
LIGHTNING (which means no purple in the seedling) and the carotene from
CHIEF HEMATITE (which means golden yellow).  This is the type of cross th=

Yes, to both.  They definitely take after their parents -- but you have t=

Yes, you can cross red with purple and get white, if both are carriers of=

the same recessive genes.  You'll probably get a lot of reds and purples,=

too, of course.  CHIEF HEMATITE comes from a long line of plicata breedin=
g,
including known carriers of recessive white.   Many good purples are
carriers, so getting a white from this type of cross is not surprising.

If they are heterozygous, their offspring may have some nice surprises.

SPARTAN is Seedling X FIREBALL.  While it might seem reasonable to assume=

that the pod parent was a red-brown Schreiner seedling, no information is=

given about it in the Checklist.  All I can say for sure is that SPARTAN
shows both carotene and anthocyanidins, and may carry some interesting
recessive traits that could show up among its children.

SWEET MUSETTE is from two of Schreiner's seedlings:  M 797-1 X H 244-C.  =
 I
doubt that anyone but Schreiner could give you a description.  =
