7 edible shrubs for improving urban biodiversity

5. Elderberry tree (Sambucus nigra ‘Black Beauty’)

From all the edible shrubs we’ve selected, our absolute favourite has to be the elder or elderberry tree (Sambucus nigra). Long revered, the elder is celebrated for its fragrant flowers and superfood berries that are both divine to cook with. If you’re looking for a bold eye-catcher in the design of an urban park, you – and the wildlife – will fall head over heels for the ‘Black Beauty’ cultivar with its stunning deep purple foliage, elegant pale pink flowers and purple black fruit. 

Native to the Netherlands, the elder has been associated with folklore and witchcraft. Its name derives from the ancient Greek wind instrument sambuca, and from the Anglo-Saxon word  aeld meaning fire as the elder’s hollow branches were used to blow the embers of a fire. An elder isn’t fussy about where it’s planted. It prefers sun but doesn’t mind some shade nor wet conditions. Resilient and fast growing, they’re an ideal shrub for establishing a design quickly, bearing fruit already after 2 years. 

If it were possible to capture the scent of summer, elderflower syrup probably comes closest. Choose a sunny day around early June to pick the large lacy clusters of flowers for your syrup – take a moment to really enjoy their heady fragrance. The Black Beauty’s dark pink buds emerge as pale pink flowers, an elegant contrast with its dark purple leaves. Be sure to make enough syrup to last into the colder months when you’re longing for summer. While harvesting, you’ll see that the insects of every kind adore elderflowers as much as we do; planting elder around a vegetable and fruit garden is sure to attract the pollinators you need. Elders are also hosted plants for butterflies and moths such as elderberry pearl moth, swallow tailed-moth and buffermine (gele tijger in Dutch meaning yellow tiger). Dried flowers make a lovely tea.

The sight of drooping clusters of ripe elderberries is an unmissable part of autumn. Leave the green ones as they’re poisonous and pick only the deep purple berries. These make the most delicious syrup (used in traditional medicine to treat colds), jam, pies and wine, and are also used as natural dyes. Birds flock to feast on the ripe berries, their droppings helping to spread the seeds. If you spot some wrinkled little brown ‘ears’ growing on older branches of the elder especially in winter, these are wood ear mushrooms. A culinary delicacy, they’re named after Judas who is said to have hung himself from an elder tree.
