Anyone who has read this blog in the last week or so will know how pleased I am with the Inula helenium that is in full flower right now. It must be the little boy in me that wonders how a seed, no bigger than a grain of sand, could become such a large, sturdy and colourful plant.

A plant adored by bumble bees

And now at nearly 1.8m tall, and 1.2m wide, the most outstanding plant in the garden by a mile!
