Seasons greetings from the travelling botanist, I’m taking a break from my travels to bring you a special blog post featuring in the advent botany. Today’s advent features Cornus mas. More commonly known as the cornerlian cherry, it is a medium-large deciduous tree of the dogwood family. Linnaeus referred to this species as both Cornus mas and Cornus mascula, translating to “male” cornel in order to distinguish it from the “female” cornel, Cornus sanguinea. It is native to South Europe as well as many parts of South Western Asia. It was thought not to be in the UK until 1551 whereby William Turner, a keen natural historian and friend of Conrad Gessner, heard that Hampton Court Palace had one in its gardens.
Cornus mas has a cold-hardiness rating of zone 4-8. The fact that it is so cold-hardy means that it is able to survive at temperatures between -25 to -30°C Celsius and is still able to flower at -20°C. The cold-hardiness has also meant that Cornus mas has been successfully introduced to countries outside of its native range such as Norway, Denmark and Sweden as well as across the UK.
Typically used as an ornamental plant, it is a bright and cheerful tree amongst the cold greys of winter. During autumn the glossy green leaves turn purple and come winter the tree boasts beautifully bright yellow flowers. The flowers appear around February to March and are typically very small (5-10mm in diameter) however they provide an important food source and a habitat for pollinators and other insects during those winter months. The flowers are replaced by green berries that ripen to a dark, rich red by mid-late summer. The berries swell to around 2cm long and 1.5cm in diameter and are very fleshy, containing just a single seed. The berries have been harvested and eaten for around 7000 years in ancient Greece, however as the small seed sticks to the flesh of the fruit it has been neglected by mass production and processing. Trees of this species are reported to live and still be producing fruit for over 100 years meaning that there are many years of bountiful harvests to be had if you find one near you.
When unripe the berries are often compared to olives however upon ripening they bear a tart flavour similar to that of cherries. Recipes from the 17th century detail pickling the berries in brine or serving them up in small tarts however the berries are also ideal for making into jams, sauces, syrups or even distilled into your own home-made liqueur or wine. According to Granny, cornelian cherry jams make a great a great alternative to other condiments with your turkey, but also suits cheese and other savoury dishes for this festive season!
I have listed some of the recipes below in case you happen to come across some of the cornelian cherry for yourself.
