Borago officinalis

Borago officinalis

Botany Photo of the Day will have brief written entries on weekends, holidays and my vacations from April through September. – Daniel

Thank you to roselea@Flickr from British Columbia for sharing today's photograph (original titled “Blue” via UBCBG BPotD Flickr Pool). Aptly named!

Although native to the Middle East, the range of borage has expanded throughout the Mediterranean region and into central and eastern Europe, along with introduction to other regions of the world. Borage is considered a neglected horticultural crop by Nuez and Bermejo; the authors point out its relatively scant cultivation as a crop, despite its many food uses. Gernot Katzer adds more details about the culinary uses of Borago officinalis on his valuable Spice Pages site.

It may be that borage has been neglected as a horticultural crop because the best customers tend to die of liver failure. Anyone thinking about eating it in quantity should note this statement from Gernot Katzer's page (linked above):


Several non-volatile components have also been identified, among those the toxic pyrrolizidine alkaloids intermedine, lycopsamine, amabiline and supinine. Pyrrolizidine alkaloids, which are extremely common in the Boraginaceae family, are powerful hepatotoxins that cause severe liver damage on chronic ingestion, often with lethal outcome. Although the total concentration in borage is extremely small (around 10 ppm in the dried herb), it has been argued that borage is an unsafe herb when used in folk medicine; the risks associated with casual culinary usage are probably negligible.

Borago officinalis - Z7 - RHS Index of Garden Plants, Griffiths

Borago, bor-a-go; derivation uncertain, may be from mediaeval L. borra or burra, rough hair in reference to rough foliage. Linnaeus states name to be corruption of corago [L. cor, the heart, ago, to act] from its use in medicine as a heart sedative.
Officinalis, of-fis-in-a-lis, of the shop [herbal]. - Plant Names Simplified, Johnson and Smith.

We have this volunteered in the garden. Enjoy its odor, but the leaves are too hairy to enjoy in a salad unless they are finely chopped.
Who knew it was so photogenic?

bev commented:

Ditto; this volunteers under our work table in the vegetable garden where I volunteer at Green Spring (public county)Gardens in Fairfax County, Va. It contributes as much as I do - it's so pretty we can't pull it up!

Eric in SF commented:

This is widespread in the Bay Area - growing in both areas where it's desired and wild in the parks.

Cherie commented:

Solanaceae?

Elizabeth commented:

In a salad, it is the flowers, not the leaves that are so enjoyable! And beautiful!

Margaret-Rae Davis commented:

What a lovely picture of Borage. In all the herb gardens I design I all ways plant Borge for the wonderful blue floweres (which are nice in salads). They self sown here in western Massachusetts
Thanks you for the great photo.

Cherie - Boraginaceae. Daniel always put the plant family as the first (and usually only) keyword at the very top, right under the date and plant name.

Other well-known members of the Boraginaceae are the Echium (many from the Canary Islands), Anchusa(many members of this genus are pretty but annoying weeds), and the fascinating Tournefortia acutiflora.

A key ingredient in the Pimm's cup.
