It is a rare generic hybrid that shows that even in plants, when white is mixed with red, the result is pink! The flowers are borne mainly in very crowded, spherical to oblong or conical inflorescences. It is many-stemmed, forming a dense, erect to sprawling or scrambling bush. The flowers make a good cutflower, looking good for a long time, as new flowers open continually. They need good light, preferably full sun. The shrubs are said to be half-hardy and might not withstand a heavy frost.
