| This link should lead you to a peony bloom time website. Since everyone's climate is different, these things tell you the bloom ORDER, how early or late each cultivar will bloom in relation to the others. So you have to figure out when one of yours blooms, and then you can approximate the date the others will bloom according to it. Of course it's different each year, and microclimates, as you noted with your 'Festiva Maxima,' also can make a big difference. Anyway, click on 'data' and then on the chart specifying bloom order. |
