Heucheraholics

I can't find out much about Heucheras, but each year at Chelsea Flower Show these seem to be more amazing colours, these ones were all snapped at Heucheraholics stand, for which they won a silver guilt medal this year. They only sell these amazing colourful leaved plants. I though it would be very cool to plant a whole bed of different colours to create a colour range in the soil !
