this is a plant called fireweed that is not something farmers like to have grow in their paddocks .. this particular plant is dying, hence the curled over flowers .. fortunately sheep will eat fireweed without any harmful effects and also they help to keep it under control .. it can poison some animals, like horses and cattle, if they eat enough of it ..
about fireweed
Beautiful colors, Roz - complimentary yellow and purple with the green thrown in - make this an excellent image. The flowers are so delicate and don't look poisonous at all!
What a beautiful image, hard to believe those little things are so dangerous! The purple background is gorgeous, really complements the yellow flowers.
