The yellow day lilies (Hemerocallis lilioasphodelus) are in full bloom at the moment. The day lilies (Hemerocallis) are a very useful group. Some have edible tubers but the flowers are the stars. They go well (and pretty spectacularly) in salads, but I like the taste best in stir fries or soups. The Chinese use them to thicken soups and stews: you can see big bags of ‘lily flowers’ in Chinese supermarkets (but beware, some true lilies are poisonous – the perils of common names). They keep this property when dried, which they do pretty well themselves on the plant. Once dry they keep forever.
They yellow day lilies are always the first into flower with me: if you grow a range of species and varieties you can have fresh flowers for two or three months.
