Re: Iris wilsonii hybrid

>>> I have grown pure species I.wlsonii and I think yours is
hybrid possibly with I.chrysographes. Pure species have not so
long standards and are very gracious held at about 30grad from
horizontal line; form of falls also is different-for wilsonii is
obovate, but on your photo it seems more likeon some forms of
chrysographes. I have grown many seedlings and have observed
such a form. I don't remember well character of marking, but
think it not take so large area of fall. <<<

Hi Edmundas, Ken and all,

On p. 5 of the color plates near the beginning of the 'Iris of
China' book by James Waddick and Zhao Yu-yang,  there is a photo
of Iris wilsonii that looks very much like Ken's.  Except the
color is not as bright. (I am working at a disadvantage since I
deleted Ken's photo (!) but I did look it up yesterday when he
posted it. )

The text accompanying this photo reads in part: "Iris wilsonii
has large flowers with angled standards. All species of Chinese
Siberian iris with 40 chromosomes hybridiaze readily in
cultivation. Pure species  can be lost as vigorous self-sown
hybrid seedlings can crowd out choice parent plants. " 

Also, in Currier McEwen's book, 'The Siberian Iris' (1996),
there are two illustrated plates (as opposed to photos) of the
two yellow 40s, Iris wilsonii and Iris forestii (plates 7 and 8
respectively). Clearly, Iris wilsonii has much larger standards
than Iris forestii in these plates by Jean Witt.  

In McEwen's book, p. 35, he writes: "Seedlings from crosses of
Iris forestii and Iris wilsonii are, of course, yellow or CREAM
colored (plate 33). Many interesting dotted and striped
seedlings have been achieved by crossing Iris chrysographes and
other dark parents with yellow parents." 

The Subseries Chrysographes is of such interest especially to
those of us who live in the northern regions where it does so
well. I wish the iris, Iris chrysographes, had a different name
since it can lead to a little confusion when discussing the 40s.
 (and me not having Ken's photo is also confusing :-).

We are in peak Siberian and TB season right now in the Eastern
Mountains. I don't want it to end.
