Tree peony 'Joseph Rock'
I have read about this great tree peony 'Joseph Rock'
(large single white flower w/ purple blotch in the middle,
very fragrant). It's been frustrating trying to
track the plant down. At first, I thought it's a
species and that it will come true from seed. Then
I learned the plant and seed are unavailable, and
that what people sell are close but not the real thing.
Can any one offer any helpful insight? I'll appreciate
any info ie, if anyone tried to grow it from seed and the
result, if anyone has one and from what the source.
