the dark one looks like bronze beauty. It is one of the ones i have. quite a large flower spike to it.
the oter might be tricolour though it has another synonym too.

Thank you Seaburngirl. As you say the dark one does have a fairly large flower spike, the handle of my trowel can be seen in the picture to give some idea of the actual size. I will now make labels to remind me of their names in the future.
