[From "A Raise Eyebrow for Striped Roses", by Darrell g.h. Schramm, pp. 13-18]
‘Tricolore de Flandre’, a Hybrid Gallica raised by Parmentier in 1844 and introduced by Louis van Houtte in 1846, shows a white background irregularly striped and splashed with poppy red and lilac or amaranth around a green button eye. The variegation is somewhat inconsistent. The flower is a full, rounded, plump and tightly packed rose with reflexed petals on a dense and bushy plant nearly without prickles. In fact, the bush in its season is studded with roses. It does well in large pots. And apparently it has somewhat of a tendency to climb. Said to be rather more vigorous than ‘Camaieux’, it grows from three to five feet high and two to three feet wide.

Rosa ‘Tricolor de Flandre’
A Gallica rose.  Scented, almost fully double, pink flowers with purple stripes.  With upright habit and growing to 90cm, it makes a good pot specimen.  [Paul (1848, 1863), Rivers (1854, 1857, 1863), Amat].
 
Horticultural & Botanical History
Introduced by Louis van Houtte in 1846.  Thomas Rivers thought little of most striped Gallica roses.  He considered Oeillet Parfait to be by far the best and ‘Perle des Panachees, with flowers of a pure white striped with lilac and red, is an acquisition; and Tricolor de Flandres, a new and very double striped rose, may be retained.’

History at Camden Park
Included in a handwritten list of roses dated 1861, probably intended for a new edition of the catalogue that was never printed.  [MP A2943].

In his catalogue of 1846, Van Houtte (Ghent) describe this variety as follows: "Magnificient mottled Provins which will be supplied for the first time this autumn. Its blooms are quite full, pompon-form, white base clearly striped poppy, lilac and amrant." It was so beautiful that he proposes a price of ten (Belgian) francs instead of 3 francs as for the other varieties! This rose is not from Van Houtte, as he did not breed any himself. Is it not in fact an obtention of his friend Louis Parmentier, from whom he distributed numerous other varieties?
In his catalogue, Verdier notes about this rose: "Very beautiful when it variegates, but unfortunately very inconstant in the soil of Paris; its bloom is then a dull uniform violet." Thomas also notes this peculiarity.

"Trocolore de Flandre": an exclusive "edition".
The Belgian nurseryman Louis Van Houtte, established in Ghent, published from 1845 onwards a magnificent magazine titled Flore des serres et des jardins de l'Europe in which the plants are minutely described and superbly illustrated. Sometimes, it is true, the "advertising" was somewhat showy: Thus for 'Trocolore de Flandre':
"The entire edition of this rose in question, has been purchased by the Van Houtte company. Its bloom, by its triple and graceful colouring, has won over, since its issue, many disinterested vote. The plant has a well-spread habit and a good appearance. It belongs to the section of the Provins. Its wood is green, scarcely prickly, firm; its foliage quite small, smooth, beautiful green. The blooms, of medium size, are well carried, numerous, very full, slightly domed and formed of almost equal petals, rounded, very tight, reflexed. The base is pure white, striped with numerous and clear stripes of pink and carmine, passing later to red and dark purple and finally to violet.....(October 1846)
