Report of the Conference on Genetics (1906)
Exhibit of Rosa Foliolosa
Maurice de Vilmorin, Paris

Rosa foliolosa of Nuttall is a wild species in Arkansas, Texas, &c., and has been too much neglected by horticulturists. It presents very distinct features—a small size, very thin wood, very elegant little foliage, with numerous and glossy leaflets. It is very late flowering and continues to bloom all through the autumn, showing bright rosy-white flowers, bearing at the same time both green and red fruits with fine fimbriated sepals. The defect of its sending out so many suckers may be corrected by budding it on the collar of some other rose.

But it is chiefly for hybridising purposes that Rosa foliolosa ought to be interesting. Crossed with some dark-coloured variety of Rosa indica it would probably give some very good results. I successfully tried its hybridisation with the red Rosa rugosa, and the result is a bush some three feet high, broadly pyramidal, with plenty of blossoms of a light yellowish-pink, produced from July to the frosts. Many other combinations might be tried.

M. Maurice de Vilmorin communicated a note on a new hybrid Rose, a painting of which he passed round for the examination of the Conference, between Rosa rugosa and R. foliolosa, which had the advantage of flowering late in the season.

Mr. Paul congratulated Mr. de Vilmorin on his acquisition.

The Chairman said he should like to ask whether the long flowering was in any way connected with not setting seed?

M. Vilmorin said it was not—it produced good seed.


The Gardeners' Magazine 49(2753): 520 (Aug 4, 1906)

M. Maurice de Vilmorin made a few remarks concerning a new hybrid rose raised by crossing Rose foliolosa with R.rugosa; one parent flowered in July, and the other in August, whereas the hybrid flowered continuously through the summer and autumn. It, moreover, made a bush of perfect habit, and had foliage that had so far been entirely free from disease or insect infestation. Mr. George Paul was interested in this production, and urged further experiments for the purpose of securing perpetual blooming roses; if single flowers could be secured he was sure doubles would soon follow.
