Spring has finally turned a corner in England now we have slipped into May. Typically, it being May Bank Holiday here, the weather is still on the chilly side (I have the heating on!) and it’s raining. The forecast promises warm weather by the end of this week, much to everyone’s relief. It has been a good year for spring flowers though and now the daffodils have given way to the most glorious (I think) wild flower displays this country puts on, for May represents bluebell time. Whilst in some locations they often appear in April if the weather is warm enough, invariably it is the non-native species that bloom first.
It is a sad fact that English bluebells are unique but being slowly but surely eroded by foreign counterparts introduced here way back in the early 1900s. Known as Spanish bluebells, they are different in many respects to our own native species but so common now, most people do not know the difference. The plants are common in people’s gardens too, as seeds can be readily purchased and easy to grow. As a consequence, they have self-seeded along hedgerows and verges and able to cross-pollinate with our native species, thus destroying their uniqueness. This is such a shame.
So, how can you tell which is which? There are four simple ways.
First is colour. In the Spanish varieties (hyacinthoides hispanica) the bell-shaped flowers are pale blue, often white, and occasionally pink. The native English (hyacinthoides non-scripta) bluebell flower is darker, more a cobalt blue. The second is the way the flowers hang on the stalks. In the foreign variety, the stem is upright with the bells flowering around it, the flower heads fairly large and open tipped and more prolific. In our native plant, the stem arches with the flowers hanging on down one side only, and with fewer bells.
The third clue is pollen: the Spanish flower has blue or green pollen; in the English variety it is white or cream. The fourth, and to my mind the most important, difference is perfume. There is no smell to Spanish varieties whilst the true English form will scent a woodland glade with a subtle, honey-like perfume that is unmistakable.
There’s nothing quite like an English wood when it is in a full swathe of blue glory. A walk through these can raise the spirit and lift the heart as they herald the onset of summer. The show is short-lived as once the leaves on the trees come out fully, the flowers vanish. It’s one of the reasons why I love painting bluebell scenes – to preserve this unique English spectacle for longer. Now, if only I could find a paint that has the same sweet perfume…
