S PRING, ALL PRETTY IN PASTELS, DOESN’T HAVE ENOUGH RED FOR ME, I suppose, which is why I like the red trillium or wakerobin, red tulips for cutting, and especially Pulmonaria rubra, the red-flowered lungwort. No fancy-pants silver-splashed foliage likes it more popular cousins, perhaps, but P. rubra is an ace of a plant, early and tough and ever-so-tolerant.
After the hellebores begin, and overlapping them, P. rubra (Zones 5-8) is the next perennial to open in the garden here each year; it’s even early among the pulmonarias, actually (most of which have blue flowers).
We’ve had many years together, and owing to the generous divisions that it’s always happy to offer, P. rubra has become one of my standbys for massing in loose sheets in the shade under deciduous shrubs, where I want cover and a little early fun, but not a lot of extra work. It spreads happily but not aggressively, and is very easy to dig out.
The maintenance regimen includes only one hard cutback a year, after flowering. Lungwort will sulk and perhaps go temporarily dormant if the area gets terribly dry, and doesn’t want to be sodden, either, which will quickly rot off the plants (as with most botanical things).
P. rubra combines well with various bulbs; I have clumps of white Narcissus interplanted in one mass of it, and everyone seems perfectly happy together.
There are named cultivars of P. rubra, such as ‘Redstart,’ and even one with variegated, white-margined leaves called ‘David Ward.’ But to me that last one’s overkill; the flowers are the point with this gem, that extra-optimistic flash of red that admittedly burns out after a good long show to pinkish-red, the sign of warmer days to come.
My only question about P. rubra: Why isn’t it more widely available? Fortunately, Joy Creek Nursery in Oregon offers it up in their great catalog. If I didn’t already have it, I know what I would do…order some, just like the other plants I rely on and have talked about lately that are listed below.
