Gertrude Jekyll

May I introduce the aforementioned Ms Jekyll, apparently a formidable gardener.

From Wiki - Jekyll was born at 2 Grafton Street, Mayfair, London, the fifth of the seven children of Captain Edward Joseph Hill Jekyll, an officer in the Grenadier Guards, and his wife Julia Hammersley. Her younger brother, the Reverend Walter Jekyll, was a friend of Robert Louis Stevenson, who borrowed the family name for his famous novella Dr Jekyll and Mr Hyde. In 1848 her family left London and moved to Bramley House, Surrey, where she spent her formative years.

The rose dedicated to her by Austen's is described thus:
The flowers of this rose start as perfect little scrolled buds and soon open into the most beautiful, large, rosette-shaped flowers of rich glowing pink. The growth is upright and vigorous and in every way reliable. The most outstanding characteristic of this lovely rose is its beautiful and perfectly-balanced Old Rose scent. This is often described as being the quintessential old rose fragrance. The foliage and growth are similar to that of a Portland Rose, with the typical Portland widely-spaced leaflets. It forms a medium sized shrub which is robust and free flowering.
