Linum grandiflorum ‘Rubrum’

A thank you to Michael Mazars of France (aka Mikl – (CRBR)@Flickr) for contributing today’s photograph of Linum grandiflorum ‘Rubrum’ via the Botany Photo of the Day Flickr Pool. Much appreciated!

Linum grandiflorum is native to northern Africa, specifically Algeria. English common names it is known by include crimson flax, scarlet flax, red flax and flowering flax. Cultivated in gardens as an annual ornamental, it occasionally escapes and naturalizes (in such places as Britain, southern Europe, California, and elsewhere in northern Africa).

If researching this taxon, you may find references to it being called Linum grandiflorum var. rubrum. This name only seems to have been used in horticulture (if you click on the link, you’ll see “hort.” after the var. rubrum part, meaning “hortulanorum” or “of gardeners”), i.e., it was never validly scientifically described and published. In order to bring the name in compliance with the rules surrounding the naming of botanical and cultivated taxa, it was shifted to Linum grandiflorum ‘Rubrum’.

    Very bright color! I wish we have naturalized here in BC:-)Is it weedy?

    What a beautiful photo! Such vibrant color. What I’d like to know is whether the flowers close on cloudy days like those of the blue flax (Linum perenne)?

    I have this in flower outside my window at the moment on the Isle of Skye (N W Scotland). I grow it every year from seed as an annual and it flowers and flowers from the end of May until it finally gives up to hard frost or snow. The flowers open and close according to the strength of sunlight and furl up at night. Utterly stunning – each petal is outlined with the narrowest band of black – so fine it is almost an optical illusion. The surface of the petals are like satin and absolutely glow… A real little gem, not showy, just stunning.

    You know, you could not have painted a more beautiful painting than this; simply nature in all its splendor! Here’s to a beautiful day.

    Very, very nice Daniel! Love the composition, and the open flower almost literally leaps out of the picture.

    This is a lovely plant and is often included in “wildflower” seed mixes in the U.S. Unfortunately, it can escape cultivation and encroach on native flora. Lovely, but keep an eye on it.
