Pulmonaria 'Opal' or 'Ocupol' has small, pale green leaves that are speckled with silver. Pale pink buds emerge in March above the small ovate leaves and these turn into clusters of pale blue flowers. This is a compact, neat plant and can be left to grow without any regular maintenance.
In general pulmonarias are well-suited for clay, chalk or loam soil that is fertile but not waterlogged. 'Opal' unlike other pulmonarias is a semi-evergreen perennial and so may lose some leaves during the autumn and winter. It grows at a much slower rate than other types but still may need to be divided every few years.
There are a variety of pulmonarias to choose from ranging from heady reds through to white and blues and some plain foliage types if all those silver spots get a bit too much. However for me Pulmonaria 'Opal' gives that little splash of welcome colour in early spring that's just right and so simply enchanting.
