The Story

Peonies originated in northern Asia, growing in what are modern-day China, Korea, Japan, and Siberia. In China, they have been grown in gardens for 2,500 years. In the West, they’ve been cultivated since the late 1700s. Dr. Alexander Fleming Peony was developed sometime before 1950 by a Dutch plantsman named Blonk, using the incomparable Sarah Bernhardt Peony as one of the parents. In naming the new plant, Blonk honored the renowned Scottish physician, who in 1928, famously left his messy laboratory to go on vacation… and returned to find he had accidentally discovered penicillin!

The Details

People are often concerned when they see ants crawling on their Peony buds. This is no cause for alarm—they are only seeking out the little drops of nectar that appear when the blossoms form. Of course, you’ll want to shake off any ants before you cut your Dr. Alexander Fleming Peonies for a bouquet for the house!

How to Grow

You’ll want to prepare the ground well for your Dr. Alexander Fleming Peony, because it will be in place a long time. Peonies are long-lived and don’t like to be transplanted. Choose a site that’s sunny and open, with soil that’s rich, deep, and well-drained. Take care not to plant too deeply. If the crown is more than an inch or two below the soil line, flowering may be inhibited. Peonies relish cold climates and, in fact, need a certain amount of low winter temperatures in order to bloom well. In hot, humid climates, they are also more susceptible to diseases.
