Bought one a couple of years ago, but had to get rid of it. It self seeded all around the garden. It looked nice at the back of the flowerbed but it went everyplace. I was even pulling them out of the lawn. The tallest one I had was about 4 foot with the flower spike about 3 foot. A neighbour was telling me it was a herbal plant that is widely grown in Australia. The leaves are soft and hairy, and the rosette of leaves at the base can grow quiet large. It looks very similar to the one I had so I hope I`m right.
