MY peonies have lasted almost 18 days!

 Most are herbaceous perennial plants 0.25–1 metre (1–3 ft) tall, but some are woody shrubs 0.25–3.5 metres (1–11 ft) tall. They have compound, deeply lobed leaves and large, often fragrant flowers, in colors ranging from purple and pink to red, white or yellow, in late spring and early summer. The flowers have a short blooming season, usually only 7–10 days.

Must be the fertilizer that Maureen spreads around every Fall!
