this has me stumped.
do the flowers open up more or do they stay 'closed'.
how big are those leaves and how tall is the flower spike?

I get the feeling it is quite large
is it scented?

Could it be Dichorisandra thyrsiflora ("Blue Ginger") ? Same family as the Wandering Jew plant (Tradescantia) which is Commelinaceae.

It could be but the rhs says it flowers in autumn.
are the leaves arranged in a spiral on the stalk?
Is the picture taken recently or is it from the autumn?

It is Blue Ginger (Dichorisandra thyrsiflora).

Sorry, Shirley! I tried to post my comment last night, but it apparently didn't go through until I hit the button again tonight! Something weird going on with my computer!

That's ok Tug ... My connection was so slow last night that I gave up on the computer!
