Hips and Haws

Rose hips in Bonnefont Cloister Detail of Rose Hips

Above, from left: The ripe fruits of the white rose tree in Bonnefont garden are held on their stems late into the fall, and provide food for birds and wildlife; the fleshy red fruits of the rose are known as “hips” and contain seeds that were used medicinally in the Middle Ages.

Apples, roses, and hawthorns are all members of a single botanical family, the Rosaceae. The fruits of the hawthorn are known as haws. The fruits of the rose are known as hips, a word of Germanic origin that appears in the glossary compiled by the Anglo-Saxon grammarian Aelfric in the ninth century.  (The Romans had designated the rose hip as malum roseum, or “rose apple”.)

While all roses bear hips, it was the fruit of wild roses such as the briar rose or eglantine (R. rubiginosa) and the dog rose (R. canina) that seem to have been used for food and medicine. The cookbook of Apicius, compiled in the fourth or early fifth century A.D., includes rose hips in several recipes, but in both ancient and medieval cuisine rose petals are used more often than the fruits. Wild roses seem to have been a famine food gathered in case of need rather than a delicacy. In the fourteenth-century Middle English translation of the Romance of William of Palerne, two lovers, William and Melior, flee to the woods disguised in bearskins, where William is given advice by his cousin—who has been transformed into a werewolf—as to what foods they may sustain themselves on, in addition to their love. It is suggested that they forage for wild plums, blackberries, hips, haws, acorns, and hazelnuts (”haws, hepus, & hakernes & hasel-notes”):

(For acorns as famine food, see last week’s post, “Pigs and Pannage“.)

William Turner, in his New Herbal of 1565, warns that those who make tarts out of hips should take heed to remove all the “down” from the fruit. These little hairs inside the hips are quite irritating to the skin. (I once made hedgerow jelly from hips, haws, and sloes, while in England, and found the process of removing the fibers from all those little hips pretty unpleasant, as well as tedious.) Dioscorides also recommended that this wooly matter be removed before the fruits were dried as a medicament to “stop the belly.”  Albertus Magnus specified the seeds contained in the hips as a remedy for diarrhea in infants.

Rose petals and oil of roses are more frequently recommended in medieval herbals than the fruits. Although garden roses were characterized as cold in the humoral theory of the Middle Ages, wild roses were classified as hot. Hildegard of Bingen says that the hips are very hot. As such, they would be considered efficacious in a complaint of  “a cold cause,” such as catarrh.) Hildegard recommends rose hips as a cure in Book LII of the Physica:

One who has pain in his lungs should crush rose hips with their leaves. Then he should add raw honey and cook these together. He should frequently remove the froth, then strain it through a cloth and make spiced wine. He should drink this often, and it will carry off the rotten matter from his lungs, purging and healing him.

Despite the flower’s ubiquity in medieval art, rose hips are rarely depicted in paintings or illuminations. However, a leafy stem of rose hips does appear in an early sixteenth-century book of hours commissioned by Anne of Brittany and painted by Jean Bourdichon. The painter shows a single “robin’s pincushion” or rose gall, formed by a parasitic wasp. (For the illumination, see the British Library Images Online.)

The gall, which is especially common on the wild field rose (R. arvensis) and the dog rose, is created when the wasp deposits its eggs in autumn. The larvae overwinter in the plant tissue, which provides both food and shelter until they hatch out in spring. This rose gall, known as a “bedeguar,” was powdered and used to treat internal ailments.

Late Bloomer

Arbutus unedo 'Compacta' Detail from The Unicorn at Bay  thumbnail Detail of Arbutus unedo in fruit and flower

Above, from left: A strawberry tree growing in a sheltered corner in Trie garden; Arbutus unedo in fruit in the woodland of The Unicorn At Bay; the evergreen strawberry tree bears flowers and fruit simultaneously in late October.

A native of the Mediterranean, the strawberry tree (Arbutus unedo) is valued as an ornamental evergreen whose late-blooming flowers and red fruits enliven the garden in late fall and early winter, when few other species are of interest. The common name derives from the description of the tree made by Pliny the Elder, who compares the fruit, with its thin, rough, red rind, to that of the strawberry, Fragaria vesca. Read more »

Two Teasels

Dipsacus sativus Dipsacus Dipsacus fullonum

Above, from left to right: The seed head of the cultivated form of teasel (Dipsacus sativus) in a bed devoted to plants used in medieval arts and crafts (2006); detail of the seed head of the teasel growing in the same bed this year; detail of the seed head of common teasel, or fuller’s teasel (D. fullonum), now in the medicinal bed.

Visitors to Bonnefont Garden are often surprised to find plants that they recognize as common weeds being carefully cultivated in the beds here. One ubiquitous weed found growing in waste places throughout this country is the common or wild teasel, Dipsacus fullonum, a plant which had various medicinal applications in the European Middle Ages.

He-Hop, She-Hop

Hop Bines in Bonnefont Cloister Column in Saint-Guilhem Cloister Male Flowers of the Hop (Humulus Lupulus)

Above, from left to right: Hop bines grown in Bonnefont Cloister garden send out new shoots in March, reaching the roofline by the end of May and dying back to the ground in late autumn; a hop bine bearing female flowers, called cones, adorns the abacus of a column from Saint-Guilhem Cloister; detail of a bine bearing a male flower.

Hop (Humulus lupulus) has been used as a vegetable (according to the Roman natural historian Pliny, the young shoots of the plant were eaten), as both fodder and bedding for cattle, as a dye, and, like its close relative hemp (Cannabis sativa), as a fiber plant. It also appears as a medicament in medieval and Renaissance herbals. The fifteenth-century Herbarius Latinus recommends hops for purifying the blood, opening obstructions of the spleen, easing fever, and cutting both headache and jaundice. However, the most important economic use of hops in the Middle Ages and at the present writing is in brewing beer. Read more »

Sometimes busy, bound by rings,
I must eagerly obey my servant,
Break my bed, clamor brightly
That my lord has given me a neck-ring.
Sleep-weary I wait for the grim-hearted
Greeting of a man or woman; I answer
Winter-cold. Sometimes a warm limb
Bursts the bound ring, pleasing my dull
Witted servant and myself. I sing round
The truth if I may in a ringing riddle.

—Anglo-Saxon riddle from The Exeter Riddle Book, translated by Craig Williamson

Immortal Fruit

Punica granatum 'Nana' Detail from the Unicorn Tapestry showing a pomegranate Punica granatum

Above, from left to right: A potted dwarf pomegranate flowering and fruiting now; a detail of a pomegranate tree depicted in The Unicorn Is Attacked; a full-sized pomegranate ripening on a tree set in the ground in Bonnefont Garden. Pomegranates are deciduous; the leaves turn a bright yellow before falling in October. By the Middle Ages, the exotic eastern fruit had long been cultivated in southern Europe. Although it is not cold-hardy, pomegranate has been grown in the gardens of The Cloisters from their beginnings.

I went down into the nut orchard,
to look at the blossoms of the
valley,
To see whether the vines had budded,
whether the pomegranates were
in bloom.
Before I was aware, my fancy set me
in a chariot beside my prince.

Song of Solomon 6:11 and 12 (Revised Standard Version)

Arum Scarum

Dragon arum in Bonnefont garden Dragon arum flower Dragon arum stems

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.
