Dr. Alexander Fleming Peony
Paeonia lactiflora ‘Dr. Alexander Fleming’Dr. Alexander Fleming Peony is a classic herbaceous perennial admired for its large, fragrant blooms and romantic color. In late spring to early summer, it produces enormous, fully double flowers in rich fuchsia-pink tones with slightly lighter outer petals and a lush, ruffled center. The blooms are heavily petaled, fragrant, and carried above the foliage in a full, elegant display that makes this variety especially popular in cottage gardens and cutting gardens.
The flowers are borne on sturdy stems above dense, deeply divided green foliage that remains attractive throughout the growing season. The plant forms a rounded, bushy clump that provides strong garden structure even after blooming has finished. Because of the large flower size, staking may be helpful during peak bloom or after heavy spring rain to support the stems.
Typically growing 2.5 to 3 feet tall with a similar spread, Dr. Alexander Fleming Peony fits beautifully into mixed borders, specimen plantings, and formal perennial beds. Its fragrant blooms are excellent for fresh floral arrangements, adding both beauty and classic peony fragrance indoors.
