I have five peonies and some sprout before the others. It's natural because some peonies are early bloomers, some middle and some late. The early ones sprout the earliest.

ok thank you

I am just starting to buy peony plants so I thought I would share with you that Sarah Berhardt is a late bloomer. This is what I found.

'Sarah Bernhardt' peony bears globe-shaped, double blossoms that fade from pale pink to soft blush on the outer petals and are occasionally flecked with carmine. When properly planted, herbaceous peonies, whose foliage dies back each fall, remain productive for decades. They are among the few perennials that don't require division, in fact, they resent disturbance. Peonies bloom from late spring to early summer for about 2 weeks; these bloom times are designated as early, mid, and late season. Free-flowering 'Sarah Bernhardt' is a late-season bloomer.
