Rosa chinensis sanguinea, flowers in waves through the year, even in the very dry soil beneath our wild pear tree. All the new growth ends in loose clusters of elegant uptight buds that open their petals in a big red flop. The single flowers are unscented. The foliage is healthy with strong red tints. An old China rose, it has been grown for hundreds of years, and with good reason. It really is a very good shrub, pretty, tough and trouble-free.
