Can you believe we're actually asking for rain in Yorkshire?! Find out what our Medieval Herb Gardeners have been up to this week in their latest blog.
14 April 2025
Monday, still no rain, and the ground is like dusty concrete. The plants are beginning to show the effects of the lack of water. Some are not getting to their usual height before they start to flower.
Being the Easter holidays, we had plenty of families visiting. We were regularly replying to the usual youngsters’ query of “Whatcha doin’?” !
Dave finished off weeding in front of the lavender 'hedge', and did some spot weeding on the thistles. Helen used her artistic skills to make a start on the new plant boards for the MHG.

Carole continued weeding from where she, and occasional volunteer, Sharon, had left off on Thursday – yes, we don’t just garden on a Monday!
The weekly plant count found 30 species in flower. Carole then spent some time deciding which plants to include in the first MHG talk of the season. The talk is on Easter Saturday 19 April at 1pm. You can book a free ticket for the talk here.
Carole and Helen also enjoyed interesting conversations with two of our visitors today. One was from the Crown Prosecution Service of Winnipeg and Manitoba, Canada. The second was with a member of the marketing team for Warwick Castle. We really do get visitors from far and wide!
Plant of the Week - Alexanders (smyrnium olusatrum)
The name smyrnium comes from the Greek word for 'myrrh', because of the smell of its flowers and seeds. It also contains 'olusatrum' meaning 'black herb', from the Latin, olus = herb, and ater = black. This is because of its jet-black seeds, which form in late summer.
The name, 'alexanders', is a corruption of the Latin (olus ater ⇒ alisander). It doesn’t have anything to do with Alexander the Great, although the plant originated in Macedonia and the Mediterranean.
It has many common names such as: black lovage, hellroot, skit, horse parsley, parsley of Alexandria, black pot-herb, stanmarch, megweed and Thanet celery.

Alexanders growing in the Medieval Herb Garden |
Alexanders is a vigorous, deciduous, hairless, clump-forming biennial. It has a solid stem up to 22 mm in diameter, which becomes hollow and grooved with age. The leaves are bright green and have toothed edges. They are arranged in groups of three at the end of the leaf stalk. The plant can reach a height of 1.5m.
In late spring and early summer, it produces branched umbels of small, greenish-yellow flowers. These emit a strong, myrrh-like scent and produce large amounts of nectar.
The fruit is round and black when fully ripe, and exudes an oil which smells of capsicum or diesel.
Alexanders will grow in any soil, but prefers full sun.
Culinary uses of Alexanders
All parts of the plant can be eaten. Its tender young shoots, which taste like a cross between celery and parsley, can be foraged as early as late January.
The leaves and stalks were used for soups, broths, and stews. The fleshy stems were eaten like celery and the leaves like parsley.
The thickened tap-roots were roasted or added to casseroles and stews, like parsnips. The buds could be pickled or fried.
The flowers could be used as a decoration in salads. The black seeds and flowers could be used as a pepper-like spice.
Alexanders fell out of favour in the 1700s. This was when celery ('apium graveolens') started being mass produced to replace wild herbs and vegetables.
By the time Mrs Beeton had compiled her “Book of Household Management” in 1861 alexanders was “used in this country in the same way in which celery is”. However, it could only be found growing wild on the sea coast, as “its cultivation is now almost entirely abandoned”.
Folklore and other facts about Alexanders
Alexanders was well-recognised in the classical world. It was recorded by the Greek natural historian Theophrastus (371BC - 287BC). The Roman writer Pliny the Elder (c23AD- 79AD) wrote extensively about its properties. It was in common use at the time of the Roman colonisation of Britain. It was one of many culinary species the Roman armies brought with them following their invasion in 43AD.
In Britain, over 150 insect species have been recorded visiting the flowers. These include many flies and bees, several beetles, butterflies, moths, and other types of insects.
On the Isle of Man, it was known as lus-ny-ollee. It was used by vets to treat animals with sore mouths.
Medieval uses*
Although mainly used as a food crop, Ancient Greek and Roman literature described medicinal uses for all parts of the plant. It was a traditional plant for cleansing the blood. It was also a digestive herb for strengthening the stomach.
Sailors used it to treat scurvy. Herbalists used it to relieve stomach and urinary problems.
Alexanders was also a remedy for headaches, toothaches, swellings of the body, cuts and bruises, asthma, consumption, and tuberculosis.
