I've added three Paeonia photos to the wiki, one of P. japonica and two of P. mascula. Take a look at: http://pacificbulbsociety.org/pbswiki/index.php/… When these plants bloom (typically in mid April) the daily temperatures are already getting up above 80 degrees F occasionally. As a result, the flowers do not last; sometimes they open late on day one, remain open throughout day two and by day three are already withering. They make handsome foliage plants. Incidentally, I have never known Paeonia japonica to set seed here. Enjoy!
