Definitely hypogeal, displaying a three-lobed leaf in its first Spring, 
assuming it was planted directly after ripening.  I have saved seed over 
the Winter (big mistake) and it takes another year to get them to germinate.

I prefer your parentage order, as this makes better sense.  Mloko x 
macro is clearly possible, but , even when we consider all of the 
variations now under P. daurica, only crosses with P. lactiflora seem 
well known, although P. 'Pageant is an P. officianalis X (P. lactiflora 
x P. macrophylla), which is then similar to your version of P. 'Athena's 
parents and P. 'Roselette (Saunders 1943) is listed as P. lactiflora X 
(P officianals x P. macrophylla).  Saunders was apparently always 
'pushing the envelope' as he lists complex parentage, but not always the 
order of the cross.  He even crossed P. emodi x P. lactiflora, which I 
have tried but never got it to take.

Reconsidering the question, it should work, as they are both diploids.

I tried to re-load it, but my password didn't work.  Gotta get a hold of 
Mary Sue!

I am truly fascinated by Paeonia, there is a certain primitive beauty 
about them, the way they dare to grow before the snow is gone.  I often 
ask myself how these ancient plants developed, as we do have tetraploid 
populations where one would expect only diploids.  I did read a theory, 
where it was proposed that during the last ice age most of the northern 
diploids were wiped out and the few surviving tetraploids, which are 
relatively common near the poles, followed the melting glaciers to 
replace the missing diploids.  This would explain the entire P. mascula 
complex, which is tetraploid and well distibuted in Russia through to 

I have a cross of P. xChamaeleon x P. kavachensis, which may lend 
support to the idea that kavachensis is a true species.  It should be a 
tetraploid, if it does belong to the mascula group, now shouldn't it?


PS: have you managed seed on P. japonica?
