The Medieval Garden Enclosed

A colony of lesser celandine (Ranunculus ficaria) growing in the orchard below the south wall of Bonnefont garden.

The shining yellow flowers of lesser celandine star the grounds below Bonnefont garden in March and April, but the blossoms and the heart-shaped leaves of this spring ephemeral will disappear altogether by summer. The tuberous roots, which lie just beneath the surface of the soil, will remain dormant until the following spring. This invasive medieval species is not grown within the walls of The Cloisters, but has long been at home throughout the northeastern United States. (See the Ranunculus ficaria page of the Invasive Plant Atlas of New England website.)

Greater celandine, or swallow wort, has an ancient association with the common European swallow; it was believed that mother birds dropped the juice of the celandine into the eyes of their blind fledglings. The plant and the bird were linked for many centuries, and celandine’s reputation as a sovereign remedy for clearing eyes and sharpening the sight outlasted the Middle Ages.??

It seems to be called Chelidonia because it springs out of the ground together with ye swallows appearing, & doth wither with them departing. Somme have related that if any of the swallowes’ young ones be blinde, the dames bringing this herbe, doe heale the blindness of it.

Plants Database. (Chelidonium majus is characterized as greater celandine, to distinguish it from an altogether different species, Ranunculus ficaria, widely known as lesser celandine.) Read more »
