Perhaps caution is in order in calling cultivars with unknown ancestry by a
species name, but this one seems pretty obvious to me.
Now, at the risk of raising some eyebrows -
As for the dogs, biologically dogs are indeed wolves, and
they should be considered the same species. There are no
reproductive barriers between them, and domestic dogs revert to being wolves
again (for all practical purposes) when they are feral for even a short
time. Given a few generations of breeding, feral dogs even start to look
like wolves again. It has always seemed ludicrous to me that we call
domestic animals by different species names from their wild ancestors. Of
course some would argue that perhaps other species of wild dog went into the
ancestry of domestic dogs, in which case they are hybrids between species, and
not of pure wolf ancestry.
This is not to imply that all domestic breeds should be called by wild
species names. In fact most plant cultivars are hybrids of multiple
species, and it is almost impossible to sort out which species are in their
ancestry. Non-the-less, they are the product of hybridizing and selecting
from wild species.
As long as 'Pink Opal' has only I. pallida in its ancestry, it is
I. pallida. Now it is possible that there are other species in its
ancestry, in which case I am wrong (thus making the case for using caution), but
I think it is not likely. 'Pink Opal' doesn't differ in any
significant way that I can see from other "pink" (perhaps more
accurately - "rose") I. pallida; just looks like another seedling of
the species to me, and probably not several generations from wild either.

Opal- use of species designation
While this may have all and only pallida in its ancesry I
calling it a pallida. It was hyridized in the garden,
not collected in
wild and I beilive , several generations from the
wild. As soon as
plants are selected for certain characteristics we
soon see things that
are different then nature.
If we used this sort of
deignation then we should be calling long
haired dashunds and
indeed all breeds of dogs , wolves, as their
genetics is 100% from wolves.
And to study wolf behavior /genetics we
should use these domestic
"Wolves"in our studies, no need to send
biologists into the wild, save a
lot of money on resesrch that way.

Nice picture. A cultivar of I. pallida - one of my favorite
Never could quite see this one as pink, even by
standards of Sass's
day, but it is "pinkish". Smells
