Horticultural & Botanical History
‘The Paeonia officinalis is a plant which has been long universally known.  It was cultivated before the time of Pliny, and has had various medical virtues ascribed to it, which seem to have been all superseded.  The single variety was not known in this country in modern times till discovered by Mr. Sabine, in an old garden in Hertfordshire. […] It is a native of hilly woods in the South of Europe, and some parts of Asia.  It flowers profusely in June, and is a great ornament to the gardens.’  [LBC no.1075/1825].  The flower shown here is bright red rather than purple.

P. officinalis var. Sabini. — It appears that a few years previous to Anderson's "Monograph of the Pæonies", in the 12th number of the Linnean Transactions, the single-flowered P. officinalis had become so rare in gardens, that it was scarcely known to writers of that period; in fact, a single-flowered form was not believed to exist in a living state until Mr. Sabine had the fortune to find a plant in the corner of an obscure old garden in Hertfordshire.  It differs but slightly from the type, the flowers exactly corresponding in colour to those of the double red, opening a few days earlier, and not lasting nearly so long in bloom; the leaves are much less undulated than the type, the plant being more robust in habit

P. officinàlis var. Sabìni.—One of the most showy of all the single ones: the flowers are extremely large, of a very brilliant crimson, with bright yellow stamens and anthers: in foliage and habit just like the last: in flower from the 4th to the 12th of June. It is a variety which should be in every garden.

Paeonia officinalis sabini. The Paeonia officinalis is a plant which has been Long universally known. It was cultivated before the time of Pliny, and has had various medicinal virtues ascribed to it, which seem to have been all superseded. The single variety was not known in this Country in modern times till discovered by Mr. Sabine, in an old garden in Hertfordshire. The late Mr. Anderson, in the valuable monograph on this superb genus in the Linnaean Transactions, has named it after his excellent coadjutor in that work, than whom no one can be more deserving of the distinction.
It is a native of hilly Woods in the South of Europe, and some parts of Asia. It flowers profusely in June, and is a great Ornament to the gardens: it may be increased by dividing the roots, and will grow in almost any soil or Situation.
