Allium triquetrum, British wildflowers, Onion weed, Three-cornered leek

200125 three cornered leek (3)

In New Zealand we call this plant Onion weed but, here in Britain, its common name is Three-cornered leek. As its scientific name, Allium triquetrum, indicates, this bulbous plant is part of the garlic and onion family, the Alliums, and triquetrum refers to the triangular shape of its flower stem.

In Flora Britannica, Richard Mabey writes that this smelly plant was ‘introduced to Britain in 1752’ and ‘began to escape into shady hedge-banks and churchyards in Cornwall in the 1860s. By the 1930s it was in Devon’ and, in 1995, Mabey found it in the Chilterns, near London. Obviously, it’s spread even further since then, as it’s jumped the border and is thriving here in Wales. These were my first Three-cornered leek flowers for 2020.

My week in wildflowers

Barren strawberry, Bluebell, British flora, British wildflowers, Common Stork's-bill, Cornsalad, Danish scurvygrass, gorse, Grape hyacinth, Petty spurge, Ragwort, Red dead-nettle, Three-cornered leek

Though the weather has been pretty miserable most of this week, I have been seeing more and more wildflowers when I’m out on my wanders.

Barren strawberry

There will be no big fat juicy red berries from this little strawberry as this is a Barren strawberry (Potentilla sterilis) (it has fruit but they don’t become ‘fleshy and red’). I can tell which species it is from the top of the leaf that’s showing – the ‘terminal tooth’ is shorter than those on either side of it.

Bluebell

Last Sunday I saw my first Bluebells (Hyacinthoides sp.) of the year, almost certainly Spanish or hybrids rather than native Bluebells, but still beautiful to my eye.

Common stork's-bill

I think this is Common stork’s-bill (Erodium cicutarium), a nice surprise growing amongst the grass at Cardiff Bay Wetland Reserve.

Cornsalad

Cornsalad is such a dainty little plant, with very delicate, pale blue flowers. I almost missed these growing by the path at Grangemoor Park and have since seen them in a couple of places. This is probably Common cornsalad (Valerianella locusta), but the only way to be sure it’s not one of the other four varieties is to check the fruit, which won’t be possible till later in the season.

Danish scurvygrass

This is Danish scurvygrass (Cochlearia danica), originally a seaside plant that has now become widespread by following the road-salting trucks along the roads of Britain.

Gorse

Gorse (Ulex sp.) never seems to stop flowering, though the truth is that there are two Gorse species and, when one stops flowering, the other takes over.

Grape hyacinth

These Grape hyacinth (Muscari sp.) have become naturalised in my local cemetery, probably spreading from one or two deliberate grave-top plantings, or from nearby home gardens. I love their blue.

Petty spurge

Petty spurge (Euphorbia peplus) is a very common little wildflower that’s often overlooked.

Common ragwort

Spotting this flowering Ragwort by the roadside near Cardiff Bay was a bright surprise. It’s probably Common ragwort (Senecio jacobaea).

Red dead-nettle

Red dead-nettle (Lamium purpureum). I’m a big fan of all the dead-nettles – the ‘dead’ in their name refers to the fact that they aren’t covered in stinging hairs!

Three-cornered leek

Allium triquetrum, the Three-cornered leek, is a pretty, if somewhat smelly flower but considered an alien invasive plant species here in Britain.
