 | Dr. Alexander Fleming Peony. The Peony Dr. Alexander Fleming, Paeonia lactiflora 'Dr. Alexander Fleming' is a double bloom peony with pink blossoms and curled inner petals. Peonies are one of the best cut flowers and are often used in the Midwest to decorate gravesites on Memorial Day. All of our peonies are widely adaptable to most soils across the country. They bloom in mid to late spring and have very large, colorful blooms that stand out in the spring garden. Peonies can handle dry to moist sites, and do best in full sun... - Dr. Alexander Fleming Peony. |
