Grafin von Hardenberg (Black Caviar)

Full Description:

Gräfin von Hardenberg draws the garden into a deeper, more intimate mood. Its flowers open in sumptuous shades of dark crimson and purple, gradually developing the velvety, almost blackened appearance that inspired the alternative name Black Caviar.

Bred by Hans Jürgen Evers and introduced by Rosen Tantau in 2001, this German variety is officially known as Astrid Gräfin von Hardenberg. Its historic-looking flowers have a full, romantic shape, while the slightly arching growth gives the plant a relaxed elegance rather than a rigid, formal appearance.

The fragrance is one of its most remarkable qualities. Rich, fruity and exceptionally intense, it has the depth associated with classic hybrid tea perfume and becomes especially rewarding when the rose is planted near a terrace, entrance or frequently used garden path.

The flowers measure approximately 6–8 cm and appear repeatedly throughout the season. At maturity, the bush reaches around 100–130 cm, making it suitable for individual planting, mixed borders, rose beds and low flowering hedges.

Gräfin von Hardenberg is also an excellent choice for cutting. Its dark, romantic flowers bring drama to bouquets and floral arrangements, while the variety’s award-winning fragrance can be enjoyed indoors for approximately five days.

Awarded the Gold Medal for Best Fragrance at the international rose competition in Rome in 2002, this is a rose for gardeners who appreciate profound colour, memorable perfume and flowers with an unmistakably romantic character.
