What a loaded question. Very difficult to give a definitive answer as there are so many variables in terms of size, shape and colour. For drama, I really like 'Liberty' (July 25)
But 'June' has to be a favourite and it's a really tough plant that lasts well all season and looks different in different light conditions. Here are my two divisions on Aug. 2.
'Jewel of the Nile' is an interesting plant that stands out for the variety of the leaves. July 3
Just a few and if you asked me tomorrow I might have a different answer.
