I have had Malaysian Monarch for four years now. It isn't planted in an ideal location, and does get shade during the day, but it always blooms nicely. I planted it next to Techny Peace and the lovely pale yellow of Techny Peace looks very nice with the watermark and yellow throat of Malaysian Monarch. I planted this combination next to Monarda 'Raspberry Wine', and I find the grouping very pleasing. The clump has expanded well, and has proved hardy in my northern garden.
All in all, it is one that I like very much.
