Spiky

The name was familiar, but the plant was new to me.

On the shore of Echo Lake, I found several large, spiky shrubs that looked like Scotch broom gone grumpy, with strong, nasty-looking spines.

Gorse, Ulex europaeus

I didn't remember seeing it in my guide, mainly because the photo there is of a huge bush in flower, but as soon as I saw the name, I remembered it.

Gorse, an introduced, becoming invasive, species.

This weedy species is viciously spiny, and it can form impenetrable thickets. It is a European species still expanding its range within our region. (Plants of Coastal BC)

I looked for it on E-Flora; the only BC specimens reported are on Vancouver Island, in Victoria, and near the Oyster River, just south of here.

A couple of things make it worrisome: first, it's flammable, and collects its own deadwood, making a ready-set bonfire. It has been used as fuel. Not good in our woods in these drying years.

After a fire, the plant regenerates itself, both from the fire-burst seed pods, and also sprouting from burnt-off stumps, which puts it into competition with our native fire-weed.

But the flowers are edible. They say.

No conocía la planta, pero sabía su nombre. Encontré una planta fuerte con espinas al borde del lago Echo, un arbusto parecido a la retama de escoba, pero más agresivo, con espinas largas y puntiagudas. Lo encontré más tarde en mi guía; es aulaga, una planta invasiva, importada desde Europa.

En el sitio web de E-Flora, las únicas plantas reportadas están aquí en la isla, en Victoria, y cerca del rio Oyster, un poco al sur de aquí en Campbell River. 

Nos preocupan un par de datos: aparte de ser agresivo, es sumamente inflamable. Las ramas espinosas detienen las ramas viejas, muertas y secas, formando un base para una fogata. Se ha usado, en Europa, como combustible para hornos.

Eso no se requiere en nuestros bosques, ya en peligro en estos años secos.

Y además, después de un incendio, la planta se regenera, tanto desde las semillas recién liberadas por el calor, como desde los tallos quemados, que brotan de nuevo. En esto pueden ocupar el espacio normalmente habitado por nuestro epilobio, que prepara la tierra para los nuevos retoños de los árboles de hojas perennes.

Pero dicen que las flores se pueden comer. Eso dicen.

I'm having to moderate all comments because Blogger seems to have a problem notifying me. Sorry about that. I will review them several times daily, though, until this issue is fixed.

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
