Welsh poppy Meconopsis cambrica is
simultaneously a native and an alien wild flower in Britain. As a component of
the Arctic-alpine flora, which probably colonised soon after the glaciers
retreated, the wild plant was mostly confined to rocky, wooded slopes in Wales,
where it seemed reluctant to spread beyond its native habitat. But over the
past five decades it has advanced rapidly through much of lowland England,
Scotland and Wales, with gardeners acting as intermediaries. It pops up all
over my garden, filling in any vacant spaces.
This is an
effortless plant to cultivate for anyone aspiring to the cottage garden style
of planting, and excellent for wildlife gardens because hoverflies and
bumblebees find it irresistible. It’s a perennial, prolific self-sower with
tiny seeds that readily establish in paving crevices and even on walls. In
recent years it has become a familiar sight in woodlands near most villages in
Weardale, integrating into the local flora.
A couple of miles
up the valley from here, in Wolsingham, it seems to be in every garden, no
doubt finding its way into local woodlands in mud carried on walkers’ footwear
and on the feet, fur and feathers of mammals and birds.
The spread of Meconopsis
cambrica illustrates how difficult it is to predict whether a plant will
become invasive; here is a species that’s slow to spread in ancestral natural
locations but which, with no apparent changes in its botanical constitution,
has readily established in a variety of habitats throughout Britain.
In 2006 Plaid Cymru
chose a stylised version of Welsh poppy as its new logo. A serendipitous
botanical choice, perhaps, for a political party with an eye to making its
influence felt throughout the union?
