My WP made almost one foot of growth this year in a single flush, despite being in a pot, and did not seem to be bothered by the compost being constantly wet due to the weather (now moved to a spot more sheltered from the rain). New foliage has remained an apple green colour rather than change to the lovely blue-green it had when it arrived last September: effects of full sun perhaps? The polar cap developed very rapidly during the second half of September.
