I've seen many persicaria's and alot of them look similar to each other but fat domino really does stand out as the flowers are noticeably wider than the others. I also have persicaria firetail and fat domino flowers for about a full month longer too.

This cultivar is said to have the largest, fattest flower spikes, in a deep showy crimson. Like the species, it starts blooming in midsummer and continues at an accelerating pace all the way till frost.

I've read that the weight of the extra large flower spikes may cause the stems to lodge. But famous plantsman Bob Brown of Cotswold Garden Flowers rates this his favorite cultivar, a 10 out of 10.

A wonderful species which is one of the very best garden plants. Vigorous but slow to spread. Very low maintenance.
Best with reliable moisture.

This is most easily propagated by division of the rhizome.
