Pulmonaria offinalis, not the most glamorous of early flowering perennials. They lurk in the background, often unnoticed, out-shone by showy daffs and moon-faced hellebores. But take a moment to study the first red turning violet flowers, hirsute sepals glistening in the soft sunlight. As the blooms mature they achieve this colour change by adjusting the pH of the petals. Just a dull old lungwort. I don’t think so.
