Heinsohn Brothers
After visiting the Pomological Institute in Geisenheim, the brothers Peter and Heinrich Heinsohn established in 1874 the nursery Gebrüder Heinsohn Wedeler Baumschulen, which still exists, on their paternal lands. It made its fame in the rose sector with the selection of an understock, the hybrid canina 'Heinsohn's Rekord'. The danish rose nursery Poulsen issued in 1938 a rose 'Andenken an Franz Heinsohn'

The selection of R. canina as understock for garden roses in the 20th century was carried out mainly in former Germany, partly also in France, Denmark and the Netherlands, and 20 forms were selected. The most well known are: R. c. 'Brögs Stachellose' (known since 1896), R. c. 'Deegens Canina' and 'Heinsohns Rekord' (since 1935), R. c. 'Kokulinsky', R. c. 'Kordes Inermis' (since 1943), R. c.

[From the article "La Rusticité des Roses", by Wilhelm Kordes, pp. 24-27]
En ce dernier hiver, de toutes les formes Canina, seule Canina Pfander demeura sans dommage. Toutes les autres: Inermis, Senff, Laxa, Brog et, en d'autres endroits, Heinsohns Rekord, se sont trouvées gelées..... Suivant les avis des jardiniers, les roses greffées sur Rugosa hollandica devraient supporter les températures les plus basses par rapport à Canina Pfander, R. Multiflora, Heinsohns Rekord, Wadenswiler Canina, Senffs Canina, Schmids Ideal, Corriifolia frobelii, Rehder (Laxa, hort), et Inermis hort. (Gamon). Cet ordre d'énumération pourrait figurer, approximativement, la résistance respective des portegreffes, envers les rigueurs de l'hiver.
