Looks like a plant in the Digitalis or Isoplexis sp. Possibly Isoplexis canariensis. http://botany.cz/cs/isoplexis-canariensis/ Or even a hybrid between the two. http://www.pinterest.com/pin/459085755737183655/ Note the seed pods forming low down on stem as the old flowers wilt, with new flowers opening higher up the stem ....just like a foxglove.
Yes, it's the new bi-generic hybrid that has been at all the outlets down here. Acanthus species produce quite different flowers and leaves, with the flowers coming out of bracts and the leaves usually much divided into lobes.
