In the Aquaponics greenhouse we are currently exploring the cultivation of edible flowers. Edible flowers are not just decorative but can contribute unique flavours and textures to a dish/drink. For example Rosemary and Garlic flowers are extremely small and delicate, but pack a punch in terms of flavour; making them a much more attractive substitute for the leaves and cloves.
Most edible flowers also feature medicinal properties. Calendula is used to prepare balms and ointments to treat ailments of the skin but the powdered petals can also be used as a vegan food colouring. Chamomile helps with anxiety and insomnia and infusions containing the small white flowers recall nostalgic tastes and aromas from our childhood. Researchers have also found that the essential oils from certain flowers can also alter our cognitive functioning; essential oils extracted from rosemary increased alertness and working memory capacity, whilst the group receiving aromatherapy with lavender oils had slower reaction times and decreased working memory capacity (1). This is not to say one is better than the other but rather the essential oils from lavender facilitate relaxation and calmness whilst rosemary’s odors may be better suited to a workingenvironment.
Certain edible flowers are precursors of vegetables; the most notable examples being zucchini and squash flowers. By harvesting these crops at the flower stage rather than the fruit stage (courgettes and pumpkins are fruits, vegetables are a social construct!) the yield of food per plant is significantly less, but it is a quicker crop to yield and can be used in exciting manners ranging from tempura to pizza. The scent of certain edible flowers can be extracted to perfume food and drinks; popularexamples include rose, orange blossom and kewra (male screw pine tree) water. These extracts are essential ingredients in Mughali (Indo-Persian), Turkish, Middle Eastern and Chinese cuisines.
As horticulturalists it is fascinating to see the various life stages our plants go through; starting from seeds all the way to the perfumed and colourful grand finale. Furthermore we hope to also learn about the nutritional and environmental requirements of each species so that we can improve on yields and quality with each harvest. Finally, we from the Aquaponics Farm and Mediamatic Eten hope to open the kitchen and bar soon so that we may finally share and present all the effort and research put into designing our menus.
