The Medieval Garden Enclosed

The ‘evergray’ santolina is cold hardy in our climate, but dislikes our wet winters. We prefer to grow this aromatic herb in pots and bring it indoors in autumn. Above, left: Santolina is also known as cotton lavender, because of its dense, whitish-gray foliage and strong fragrance; Right: A santolina topiary made from a dwarf form of the species.

A compact, woody plant of dry ground and stony banks, the Mediterranean santolina (Santolina chamaecyparissus) is cold hardy in our USDA Zone 7 gardens, but dislikes wintering over in wet soil; we prefer to grow it in pots and bring it indoors in autumn. Santolina’s slender stems are densely covered with short, thick, cottony leaves. This low-growing evergray species lends itself to shaping and shearing, and was widely used as an ornamental edging plant in Renaissance knot gardens. It’s also an excellent subject for topiary work, especially the dwarf form of the species, S. chamaecyparissus ‘Nana.’

These small bulbs of Tulipa biflora, a species native to the Southern Balkans and Southeastern Russia, are to be planted today in Cuxa garden, the only one of our three gardens in which  post-medieval plants are grown. The tulip did not reach Europe until the sixteenth century.  Photograph by D. Larkin

Tulips, spring-blooming crocuses, winter aconites, fritillarias, and other bulbous plants native to Asia came too late to Europe to find a home in the medieval plant collections in Bonnefont and Trie gardens, but they do have an honored place in Cuxa cloister garden. Cuxa has been the main ornamental garden for the Museum since 1938, and has always included both modern and medieval plants in order to provide a continuous display from early spring until late fall.

The hot, dry weather that has us struggling to keep the gardens watered is all too welcome to the two-spotted mite, Tetranychus urticae, a worldwide pest of crop plants, ornamentals, and houseplants that is as much at home in greenhouses and apartments as it is outdoors. Two-spotted mites, along with other members of the Tetranychus family, are commonly known as spider mites. They are arachnids but are more closely related to ticks than to spiders.

Hops (Humulus lupulus), considered today to be crucial to beer brewing, were not commonly used until the fifteenth century. Before that time, brewers added different herbs, such as alecost (Tanacetum balsamita), to their beer to improve its flavor. Several of these medieval brewing herbs can be found in Bonnefont garden.

Ale is made of malte and water; and they the which do put any other thynge to ale then is rehersed, except yest, barme, or godesgood, doth sofystical theyr ale.

—Andrew Borde, The fyrst boke of the introduction of knowledge, 1452

Beer was a staple drink for medieval Europeans, as it provided much-needed calories to the often undernourished population and was cleaner and safer to drink than water. Then, as now, beer was made by brewing malted barley in boiling water to make sugars more available for yeasts to consume (see an image of Jorg Prewmaister tending his brew in a page from a fifteenth-century German manuscript, Amb. 317.2). This sugary, malty potion, known as “wort,” eventually becomes beer after the yeasts eat the sugars, releasing carbon dioxide and alcohol as byproducts of fermentation. On its own, wort is fairly flat in flavor, so brewers add additional ingredients, such as hops and spices, to enliven a beer’s taste.

Many of the healing herbs, flowers, and foodstuffs mentioned by the twelfth-century Benedictine abbess Hildegard of Bingen in her great work Physica are grown in Bonnefont garden at The Cloisters. Above, from left to right: Field peas (Pisum sativum arvense, variety ‘Blue Pod Capucijners’); Madonna lily (Lilium candidum); milk thistle (Silybum marianum).  Photographs from the Gardens archives.

It is the first book in which a woman discusses plants and trees in relation to their physical properties. It is the earliest book on natural history to be done in Germany and is, in essence, the foundation of botanical study there. It influenced the 16th-century works of Brunfels, Fuchs, and Bock, the so-called “German fathers of botany,” but the fact is that German botany is more indebted to a “mother.”
—Frank Anderson on the Physica, from An Illustrated History of the Herbals

Certain plants grow from air. These plants are gentle on the digestion and possess a happy nature, producing happiness in anyone who eats them. They are like a person’s hair in that they are always light and airy. Certain other herbs are windy, since they grow from the wind. These herbs are dry, and heavy on one’s digestion. They are of a sad nature, making the person who eats them sad. They are comparable to human perspiration. Moreover, there are herbs which are fatal as human food . . . they are comparable to human excrement.
—From Book I of the Physica, translated by Priscilla Throop

Hildegard of Bingen, Benedictine abbess, visionary, poet, dramatist, composer, and the most learned woman of the twelfth century, wrote the Physica, or Natural Science, about the year 1150. Read more »

The monarch is the most widely known and readily recognizable butterfly in the eastern United States. Between August and November each year, virtually the entire North American population of the species migrates to winter roosts in fir forests in the mountains of Mexico. Above, from left to right: Ventral view of an adult monarch feeding on a Japanese anemone in Cuxa garden; dorsal view of a male monarch hovering near a crabapple shoot; ventral view of a monarch feeding on a tubular flower of Abelia x grandiflora. Photographs by Corey Eilhardt.

The annual northern and southern migrations (see image) of the monarch (Danaus plexippus), the most beloved and familiar of North American butterflies, are monitored not only by professional lepidopterists, but also by many citizens and students across the country. In late summer and autumn, monarchs in the millions make for their ancestral wintering roosts in forests of oyamel fir trees (Abies religiosa) which grow at heights of ten thousand feet in the Sierra Nevada mountains of Mexico.

Above, left to right: Berry-bearing catchfly (Cucubalus baccifer) flowering in a shady bed in Bonnefont Garden in July; a detail from the foreground of The Unicorn is Killed and Brought to the Castle showing the catchfly in flower and fruit behind the forelegs of a hunting dog; the shiny black fruits, which give the berry-bearing catchfly its name, ripening in August.

Berry-bearing catchfly (Cucubalus baccifer) is a pretty, lax-stemmed little plant that scrambles over and through the hellebores, ferns, and other shade-loving plants growing in a small bed under the east wall of Bonnefont Garden. We would be hard put to find a home for it anywhere else in Bonnefont, which is organized by use, since we haven’t been able to document either any medieval medicinal applications or any magical or symbolic attributes associated with it.

Above, from left: dragon arum (Dracunculus vulgaris) growing in Bonnefont garden; detail of the spathe and spadix common to arums; detail of the reptilian markings on the stems.

Arums and other members of the botanical family Araceae are fly pollinated, and their flowers imitate both the color and the smell of rotting meat in order to attract pollinators. The little cuckoo-pint featured in last week’s post is by no means the most fetid member of the family. Cuckoo-pint’s enormous tropical cousin, Amorphophallus titanum, notorious for its overpowering stench, is native to Sumatra.  The titan arum is also cultivated in conservatories and gains worldwide attention when it blooms in botanical gardens like Kew.

Of all the spring-blooming “cuckoo plants” (see “Sumer is Icumen In,” April 3, 2009) associated not only with the bird but with magic, sexuality, snakes, and death, the cuckoo-pint or wake-robin is the most famous. Read more »
