Paeonia mascula

First, to follow up on Max's comments on our tree peony
/(Paeonia suffriticosa/), it's been featured on our website
and facebook if you want to see it in full glory; these have
bloomed reliably and profusely for many years here. We also
have a very reliable and prolific stock of a herbaceous
Japanese/Paeonia lactiflora/ that we often offer at our
plant sales. In other words, it is possible and even easy
to get fantastic blooms in our rather benign climate without
putting ice on the plants in winter.
