Red, Yellow and Blue


There a few spectacles in the British countryside that rival a field of poppies in full bloom. There are two fields at Warkworth on the Northumberland coast that are currently ablazed with these scarlet flowers. Like many plants, poppies produce seeds that can remain dormant in the soil for decades. They require light for germination, so only burst into life after they’ve been brought to the surface by the passing of a plough. Poppies belong to a group of arable weeds that includes corn chamomile, corn cockle, corn flower, corn marigold, bugloss and henbit whose flowering depends on regular soil disturbance, so they have always been a feature of agricultural landscapes since farming first began. In Victorian times all these species were very common, but the development of efficient seed cleaning technologies for cereal crop seed production and the advent of effective modern herbicides have removed them from fields so efficiently that many are now rare. Poppy’s vast seed output has been its salvation. Poppies survive seed burial for long periods and are often revived temporarily when new roads are cut through former agricultural land, or when grassland that was long ago planted with wheat and barley is freshly ploughed.


Behind the dunes at Warkworth, about half way to Alnmouth, there's currently another wonderful floral display in a patch of swampy ground. A single yellow flag iris (above) is a thing of beauty, but half an acre of them in full bloom is something else.......



And a little closer to Warkworth, in a corner of a field that has been left unplanted, there's the most stunning display of bugloss, a cornfield annual that occurs sporadically in the North east but here grows in such abundance that about a quarter of an acre is tinted with forget-me-knot blue.


We lament the fact that some individual wild flower species are becoming rare, but it's even more regrettable that massed floral spectacles like this, once common, are now few and far between...

Warkworth Sand Dune Flora










The sand dune system at Warkworth hosts a fine flora in early summer. The top picture shows biting stonecrop Sedum acre, whose succulent leaves allow it to thrive on bare sand in drought conditions. Below this is wild thyme Thymus serpyllum, which releases a wonderful herbal fragrance on hot days and hums with bumblebees visiting it flowers. The next flower down is viper’s bugloss Echium vulgare, whose bristly leaves prevent rabbits from grazing it. This too is a magnet for bees and makes an excellent plant for a bee-friendly wildlife garden. It’s a biennial, producing a rosette of leaves in its first year and a flower spike in the second. The seeds persist for a long time in the soil – I introduced some into my garden about 20 years ago and occasional seeds still germinate, without me ever having sown it again. Behind the dunes at Warkworth there’s a remarkable freshwater swamp, filled with the largest population of yellow flag Iris pseudacorus that I’ve ever seen – it must cover the best part of an acre and just now there are hundreds of plants in full bloom.
