It's time for the latest blog from our dedicated team of volunteer gardeners at Pontefract Castle.
Find out more about their blog series here.
This week it was back to weeding. We made sure that we didn’t accidentally dig up the clary sage, borage, marigold and winter savory seedlings that are starting to come through. These will later be potted-on and sold on our sales barrow. We also continued deadheading the marigolds to encourage more flowers.
The mullein plants are starting their statuesque and heavenward climb. They will soon be putting out their yellow flowers. Unfortunately, the largest specimen is having its leaves shredded by the caterpillar of the mullein moth (cucullia verbasci). Hopefully, the flowers themselves won’t suffer too much.

Plant of the Week - Foxglove (digitalis purpurea)
Digitalis purpurea was named by the Swedish botanist Carl Linnaeus in 1753. 'Digitalis' comes from the Latin word 'digitanus', meaning 'finger' for the thimble-shaped flower. 'Purpurea' refers to the colour of the flowers, which are often purple (though sometimes white).
There have been many suggestions for where the name 'foxglove' comes from. It is an ancient name and exists in a list of plants from the time of Edward III (1327-1377). The prefix 'fox' has most likely been miscopied over time from 'folks'. To our fourteenth century ancestors, these were the fairies. 'Glove' may have come from the Anglo-Saxon 'gliew'. This was the name for a musical instrument consisting of many small bells. So, put the two together and you could get ‘Fairy Bells’, one of its many common names.
All parts of the foxglove plant are poisonous. Care should be taken when handling it.
Foxgloves are native to the UK and Europe. It is a biennial or short-lived perennial, evergreen, herbaceous plant. It will grow in full sun or partial shade in any moist but well-drained soil. It grows in any aspect but north-facing. It often grows where the soil has been recently disturbed, like the field poppy.

Foxgloves growing in the Medieval Herb Garden |
The leaves are green, spirally arranged, simple and oval. They are 3.9 to 13.8 inches long and 2 to 5 inches broad. They have a toothed margin. The leaves are covered with grey-white hairs, giving it a woolly texture. The foliage forms a tight rosette at ground level in the first year.
The flowering stem, developing in the second year, is typically 3.3 to 6.6 ft tall. The flowers open first at the base of the stem and graduate upwards. They are arranged in a showy, terminal, one-sided, elongated cluster. Each flower is tubular and hangs down. The flowers are typically purple, but occasionally white. The inside surface of the flower tube is heavily spotted.
There are no culinary uses of foxgloves as they are very poisonous!
Folklore and other facts about foxgloves
In the Scottish borders foxglove leaves were laid around babies’ cradles to protect them from witches. It is said that creating a boundary of foxgloves keeps the evil eye away. In Shropshire, they were put in children's shoes for the same reason.
A Welsh legend explains why foxgloves bend and sway. As the flower is sacred to the fairies, it has the power to recognize them. It bows in deference to them as they drift along.
Foxglove has a long association with witches and witchcraft. It is believed that foxglove can enhance psychic abilities and facilitate spiritual growth and intuition.
Larvae of the foxglove pug (Eupithecia pulchellata), a moth, eat the flowers of the common foxglove. The caterpillars of this moth crawl into the newly opening flowers, one caterpillar to a flower. It then spins a silken web over the mouth of the flower, sealing it. The caterpillar then proceeds to feed on the stamens and developing seeds.
In Britain, other species of Lepidoptera (winged insects) have been recorded eating the leaves. These include Mellicta athalia and Xestia ashworthii.
Medieval uses*
Foxglove was one of the many herbal remedies used by the ancient Romans. Its use for the treatment of heart failure has been traced back to the 900s AD in Europe. However, digitalis was not widely used for this purpose.
The plant’s leaves and flowers have anti-inflammatory properties. They were used to relieve pain. They were also used (with care) for kidneys and various urinary conditions, abscesses, asthma, epilepsy, tuberculosis, constipation, headache, spasm, burns, boils, headaches, removing excess phlegm and mucous, paralysis, stomach ulcers and open wounds.
Bruising the leaves and binding them around old sores would help to cleanse, dry and heal them.
However, overdosing could result in vomiting, diarrhoea, delirium and death.
