French Historic Tall Bearded Iris Mademoiselle Schwartz

En 2012 Lawrence Ransom m’a fait parvenir un lot d’iris anciens qu’il avait reçus du Parc Floral de Paris lors de son inventaire de la collection Simonet. Un plan de plantation figurait au dos du bordereau de livraison de ces iris, noté d’une belle calligraphie, avec la précision et la rigueur qui sont celles de Lawrence.

Un rhizome avait été envoyé à Phi Edinger quelques années auparavant (de Lawrence via Michèle Bersillon qui s’était gentiment chargée des modalités d’exportation).
L’identification de cet iris est donc depuis longtemps  à l’étude des deux cotés de l’Atlantique. Il a voyagé incognito sous la fausse identité de ‘Lady Foster’.
 
Phil Edinger et moi-même avons abouti à la même conclusion sans nous consulter. L’iris est en réalité ‘Mademoiselle Schwartz’ (Denis 1916)
"Mademoiselle Schwartz" a tous les atouts de la beauté juvénile qui a bu à la source de Jouvence. La taille élancée, le teint clair, une beauté immuable.
La pureté de la fleur, sa couleur délicate, les fossettes discrètes de sa gorge sont les garants de la beauté intemporelle des œuvres d’art majeures qui suscitent l’admiration et laissent sans voix.

In 2012, Lawrence Ransom sent me a selection of historic iris that he received from the Parc Floral de Paris during his inventory of the Simonet collection.  A plantation diagram was included on the back of the shipping list sent with these irises, with precise annotations written in beautiful calligraphy by Lawrence. 

Several rhizomes of one cultivar were purchased from Lawrence by Michèle Bersillon at the request of Phil Edinger, cultivated in Michèle's garden and then sent on to Phil the following year in order to comply with export regulations.  The identity of this particular iris had been in question on both sides of the Atlantic for some time and it was both purchased and sent under the false identity of "Lady Foster"

Phil Edinger and myself had come to the same conclusion without comparing our information.  The mystery iris is, in fact, "Mademoiselle Schwartz" (Denis, 1916).  "Mademoiselle Schwartz" has all the qualities of a young beauty who who has consumed water from the Fountain of Youth: slender and tall, delicately coloured and of unchanging beauty.  The flower's purity, its delicate colours and the discreet dimples of its throat are marks of the sort of timeless beauty that characterises those admirable major works of art which leave one in awe.

Pallida X Ricardi.
A light blue overlustered with pink.
This magnificent Iris, the work of the French amateur, Mons. Denis, is considered to be the best of his many successful seedlings. It is tall, possibly one of the tallest Irises in cultivation, with finely poised spikes much branched and bearing beautiful, durable blooms of Pallida form. Larger than Caterina and more freely inclined to bloom; wonderfully qualified for mass display. The growth of this plant is rapid and vigorous even in the North; the foliage is yellowish green.

Pale mauve. One of the most artistic Irises. Flowers of good size and form. One of the best irises in commerce, although we believe Mother of Pearl will prove more satisfactory due to its hardier, more vigorous growing habit. The color is somewhat similar.

....The first enthusiast to appreciate this fact, and to put it into practice, was Mons. Denis, who, living on the Mediterranean, near Marseilles, was well located to grow the species Riccardi satisfactorily. He has produced many seedlings using Riccardi as a parent, some thought difficult to grow well, are admittedly beautiful varieties. Perhaps the best known are :-  Mdlle. Schwartz 1916 (Riccardi X pall.dal) which is to be found in many collection of Irises, and which in spite of it's Riccardi parentage is tolerably hardy. 3ft.6in to 4ft.
